CHAPTER XVI
EFFECT OF IMPROVEMENTS IN METHODS OF PRODUCTION
_Displacement of Labor and Capital by Inventions._--Inventions are "labor-saving." Employers are engaged in a race with each other in reducing the outlays involved in producing goods, and a common way of doing this is to devise machinery that will do what laborers have heretofore done. The same thing is accomplished by developing cheap sources of motive power or introducing new commodities which are good subst.i.tutes for dearer ones. Mechanical automata have at a thousand points taken labor out of human hands; electricity, which is "harnessing Niagara," may at some time harness waves and winds and make them turn the literal wheels of mechanical progress. Such things, by causing a given amount of labor to produce a larger amount of consumers" wealth, are product multipliers; but this is the same thing as saying that they yield a given product at the cost of less labor, and as we more commonly see their effect in this light, we call them labor savers.
_Why Labor Saving is not always and everywhere Welcomed._--To an offhand view it would seem that product multiplying is the greatest blessing that, in an economic way, can come to humanity; and if general and permanent effects be considered, it is so. The solitary hunter who has to catch and club his game would get unqualified benefit from the possession of a bow and arrows; the fisherman would get the same benefit from a canoe, the cultivator of the soil from a spade, etc. Society in its entirety is an isolated being and derives similar gains from engines, looms, furnaces, steamships, railroads, telegraphs, etc. Yet there are persons within the great social organism to whom the benefit _from one special improvement_ may be small and the cost great. There are none who are not better off because of _all improvements_ past and present.
_The General Demand for Labor not Lessened._--It is a matter of common experience that new machines are labor displacers. At its introduction an economical device often forces some men to seek new occupations, but it never reduces the general demand for labor. As progress closes one field of employment it opens others, and it has come about that after a century and a quarter of brilliant invention and of rapid and general subst.i.tution of machine work for hand work, there is no larger proportion of the laboring population in idleness now than there was at the beginning of the period.
_A Voluntary Reduction of Toil Desirable and Probable._--A full study of the effects of technical progress will show that there is never a reduction of the general field for employment in consequence of it.
There is an increase of pay, and this causes a certain unwillingness to work for as many hours as men formerly worked; and there is also a change in the nature of the operations that labor performs, which tends in the direction of more comfort and less painful toil. For the famous statement of J. S. Mill that "It is questionable if all the mechanical inventions yet made have lightened the day"s toil of any human being" we may safely subst.i.tute, "It is the natural tendency of useful inventions to lighten the toil of workers and to give them, withal, a greater reward for their work." Mechanical progress is the largest single ground for hope for the future of laboring humanity, and by its effects, direct and indirect, it has already insured a great alleviation of toil, with an increase in its rewards. It has helped to counteract the world crowding that for a century has gone on and the diminishing returns from agriculture which the crowding entails. Inventions may make disturbances, and their better effects may be temporarily and locally counteracted; but a society where compet.i.tion rules is sure to secure the benefits in the end and does, in fact, secure them in greater and greater measure as the years go by. Such are some of the theses which research will justify.
_Facts concerning Disturbances incidental to Progress._--We have first to take account of the disturbances. They are prominent in economic discussion and const.i.tute the subject of one of the grave indictments brought against the system of compet.i.tive industry. They have actually caused great hardships in the past, as skilled handicraftsmen have seen machines come into use which, for rapidity and accuracy of work, excel the best results that long apprenticeships formerly gave. Now that machinery has possession of most of the field, there is no longer the former opportunity for displacing hand workers; but the remainder of hardships incidental to progress is not to be overlooked. This part of the dynamic movement involves present local sacrifices for the sake of future general gains. Here, therefore, there are developed antagonisms of interest which may hinder progress and, if they were extensive enough, might conceivably throw a doubt over the future of the working cla.s.s. While there is no great disposition to question the ultimate benefit which mechanical progress insures, there is some uncertainty as to the process by which this benefit is extended to workers and there is a struggle to avoid the immediate cost. There is, in some quarters, a disposition to rate the cost so highly as to draw the inference that we need to adopt a socialistic plan of living for the sake of enabling workers to avoid the hardships and secure the benefits of "labor saving." It will appear, however, if we grasp the essential facts of what we may call the dynamics of method, that the tendency of it is to reduce the burdens which progress entails, and to diffuse a large share of the benefits of it among the working cla.s.s.
It will further appear that the socialistic plan of organizing industry would at least throw a doubt over the progress itself.
Nothing, on the whole, puts the future of industry conducted on the compet.i.tive plan in a more optimistic light than the fact of the progress in productive methods which it insures. It is the strongest guaranty of a "good time coming," in which all humanity will rejoice when it comes and should rejoice by antic.i.p.ation.
_The Law that insures the Survival of Beneficial Processes Only._--It is self-evident that wherever there is a saving of labor needed to make a given amount and kind of product, there is an increase in the possible product that is created by the aid of a given amount of labor. If workers themselves get a share of the gains, this fact will show itself through that beneficent shortening of the working day to which we have alluded. The men will be unwilling to stand the weariness and the confinement of working through too many hours and will be inclined to take more holidays and vacations; all of which, when it comes about in a natural way, is an indication that the industrial organism as a whole has put its hand on a new and powerful lever and is enriching its members by means of it. It does, however, have to change the character of its work, and this means that some labor has to be transferred from one subgroup to another. The laborer displaced by an invention at a particular point continues to be wanted somewhere. When he and others have found their new employments, the good result appears,--the increase and improvement of goods produced,--and society as a whole then gets the benefit which would come to an isolated worker who, without remitting his labor, finds his appliances growing better and the fruits of his labor growing larger.
The collective body gets a greater income than before, and the workers share in the gain.
_Importance of the New Forms which the Social Income Takes._--This increasing income takes the form in which society now requires it, and it is this which brings about the readjustment of labor--or the changes in the amounts of labor used in particular subgroups--which have caused hardship in the past.
_Nature of the Incidental Evils to be Dreaded._--The problem we have to face is a danger that labor may be displaced either (1) from the particular point within a productive establishment at which it is now working, or (2) from the productive establishment as a whole, or (3) from a subgroup, or (4) from the general group of which the subgroup is a part. Out of industrial society in its entirety it cannot thus be forced. There is a case in which the men whose crafts are supplanted by machines may all stay where they are and operate the machines; but that involves forcing other men to change their occupations. There are more cases in which these men may stay in the mill or shop that employs them, but not in the same department of it. There are still more cases in which they may stay in their original subgroups, and in a majority of cases they may stay in their general groups. In every instance there are places for them in the working society.
_Local Expulsions of Labor._--When a single employer who is one of many compet.i.tors in an industry adopts an important labor-saving device, it may be possible for him to keep all his men employed and to let the improvement show itself wholly as a means of increasing the output. He may secure a machine which will do what twenty men formerly did. If it were possible to cut the uppers of a dozen shoes by the quick stroke of a single die, the machine that carried this armature would do the work of perhaps twelve knives handled by that number of skillful workmen. If the original number of men were retained in the cutting department, and if each of them were furnished with the new appliance, it would mean that twelve times as many uppers would be cut as were cut before the change was made. There would, of course, be no use in trying to do so much cutting of uppers for shoes, without doing twelve times as much sewing, welting, making soles and heels, etc., and to secure all this at once would require a twelve-fold enlargement of the manufacturer"s plant. This is too much to secure at once. The manufacturer might perhaps double the output of his mill and nearly double the number of his employees, but that would require only two of the twelve cutters he formerly had. The new workers would be in parts of the mill other than the one where the great saving of labor was effected. Ten men would be removed from the cutting department, and the two left there would cut, by the aid of the new machines, twice as many uppers as the whole number cut before, and that would require the furnishing of a double number of all other parts of the shoes and a double working force to make them. The ten men liberated from the cutting department would be available for this purpose, and new ones would be brought in and set sewing, pegging, lasting, welting, etc. Within a single establishment, therefore, a radical saving of labor at one point usually involves some shifting of labor from that point to others, though it may increase the total number employed in the establishment which secures the economical device.
_The Effect on a Subgroup of an Improvement by One Entrepreneur._--If an employer who has this experience is one of a hundred in the shoemaking industry and the only one who secures the cutting machine, the market will receive as large an increase of the product as would be involved by multiplying the output of his mill by two, without requiring that the price should be more than slightly reduced. An improvement which is monopolized for a time by a single _entrepreneur_ seldom renders it necessary to reduce the aggregate of the labor in his employment. Far more often it makes it for his interest to increase the number and to put new labor in every part of the plant where no improvement in method has been made. It is often the fact, however, that labor has to abandon other establishments in this subgroup, and enough of it may do so to cause the amount in the entire subgroup to become somewhat smaller by reason of an improvement. In the case of a single employer there is a bare possibility that no one should be moved, in consequence of an economical invention, even from one part of the mill to another. The manufacturer of our ill.u.s.tration might even keep his twelve cutters at work after the introduction of the machines referred to and do twelve times as much cutting, provided that he could quickly increase his output of finished shoes to twelvefold its former amount. There are practical reasons why he could almost never do this; but if he actually did it, he might, by some reduction in the price of shoes, find a market for this increased product. If the reduction of price were great, some compet.i.tors would probably go at once out of the business; but it is never the policy of a successful producer to make unnecessary haste in reducing prices, and, as a rule, the reduction is gradual. The increase of product from the very efficient mill must cause a certain reduction in the rate at which it sells its goods, and this is apt to force manufacturers who are particularly ill equipped and cannot keep pace with the rate of improvement which their enterprising compet.i.tor establishes to go out of business. They thus relieve the market of so much of the product as they have contributed and make a place for the increased output of the newly equipped mill.
In such a case the total output from the subgroup is not very greatly increased, and the price of the product does not need to be greatly reduced.
_Standard Prices fixed by Cost in the most Economical Establishment._--It is a vitally important fact, as we shall soon see, that the price of an article is, in a dynamic society, always tending toward the cost of making it, not in the most inefficient establishment, where it is produced "at the greatest disadvantage,"
but in the most efficient one of all. The ultimate effect of any great improvement is naturally to close the shops of _all employers who do not adopt it or get an equivalent advantage of some kind_. Ultimately the whole subgroup will be in the state of efficiency it would have reached if the improvement had been adopted by every _entrepreneur_ on its first appearance.
_The Effect of an Improvement in Production which is quickly adopted by a Whole Subgroup._--When an improvement is immediately adopted, not by one employer merely, but by all employers in a subgroup, it is likely to cause a quicker displacement of labor from the subgroup as a whole. A very economical machine introduced by its inventor or manufacturer and quickly adopted by all employers at _A""_ would nearly always force a certain number of laborers to leave that industry and find employment elsewhere, if it were not for one commercial fact, namely, the reduction in the price of the product and the consequent enlargement of the demand for it.
_How Labor may be displaced from a General Group._--The amount of _A"_ that can be created depends on the amount of _A_ that can be furnished as material to be transformed into _A"_, and also on the amount of _A"_ that will be taken for conversion into _A""_. This again depends on the amount of _A""_ that will be accepted by employers at _A"""_ and sold in this last form to the consuming public. If the market for _A"""_ cannot be much increased by a moderate reduction of the price of it, some labor may have to go into the group of _B_"s or _C_"s; and in any case there must be new labor in _A_, _A""_, and _A"""_ if the product of _A"_ is increased. We can now measure the difference between the effect of the adoption of an improvement first by one employer and much later by others, and that of the quick adoption of it by all. In this latter case there is not much delay in increasing the output of the goods, and the market for them does not have time to grow larger because of the growth in the numbers and the wealth of the community. Unless the present market will take an enlarged quant.i.ty of the finished goods without requiring that the price should go below the new cost of making them, some labor will have to leave the general group.
_How Patents may Cause an Increased Displacement of Laborers._--What we often see is the nearly simultaneous adoption of a labor-saving device by all leading employers in one industry. Something like this takes place when the makers of a valuable machine retain the patent on it in their own hands, and press the sale of it on all the producers who have use for it. In this case, however, the makers usually put the price of the machine at a figure that, while it affords an inducement to buy it, does not reduce the cost of the goods that it helps to make enough to cause a great increase in the demand for them. The owners of the patent on the new appliance charge for it "what the traffic will bear"; and until the patent runs out, the users of the machine have to sell their goods almost at as high prices as before. If the machine enables one man to do the work of a dozen, eleven men must find other things to do. They could find them in their own industry if the product of it were enlarged in consequence of the use of the machine; but if the high price of the patented machine prevents this, they must go elsewhere. When the patent runs out, there is likely to be a considerable enlargement of the industry, and how important this fact is we shall soon see.
_How Improvements which call Labor to a Particular Establishment may displace Labor from a Group._--Another typical case is afforded when some one employer has for a time the exclusive use of a labor-saving device, and pushes his production to the utmost in order to get the full benefit from it. Here are seen the more characteristic effects of such an improvement. It _draws labor to_ the employer who for the time being monopolizes the new instrument of production, but it _turns labor from_ the subgroup of which this employer is a member. He enlarges his output and in time this reduces the price of the product.
In the field there are marginal mills, or those so antiquated, ill situated, or badly run that, with their product selling at the former price, they could barely hold their own; and now that the price is reduced, they lose money by running. They have to cease operating, and this makes practicable a further enlargement of the product of the efficient mill. Much labor goes thither, but some part of that which leaves the abandoned mills betakes itself to other subgroups. Not often, indeed, does it have to go to other general groups. The cheap transformation of the material _A_ into _A"_ enlarges the market for _A"_ and calls for more labor at _A_, and it involves more at _A""_ and _A"""_. If the change of method had been gradual, the growth of the social demand for _A"""_ would probably have precluded the need of sending any labor out of the entire group of _A_"s. Even a rapid change often sends labor out of one subgroup into other subgroups of that series rather than into other general groups.
An improvement that should reduce the cost of converting leather into shoes would, by the sale of the shoes, call for more leather, more cattle, more appliances, more tanning, and larger buildings for shoe factories, furnished with more shoemaking machinery and greater motive power, even though the particular machines which were improved by the invention had become so much more efficient that no more of them were needed. This depends on the extent to which a certain reduction of cost of a product enlarges the market for it.
_Principles Governing the Enlargement of the Effectual Demand for One Commodity._--In determining how much a reduction of the price of a single article will at once enlarge the market for it, there are two things to be considered, namely, the elasticity of the want itself to which the article caters, and the extent to which an article catering to a particular want may be subst.i.tuted for other articles designed to satisfy the same one. The desire for jewels and other articles of personal adornment is very expansive, and a fall in the price of any one article of this kind causes a relatively large increase in the consumption of it. Since the want to which a costly ornament caters is thus elastic, the cheapening of all articles that cater to this want would enlarge the consumption of all of them. The cheapening of a particular one of these articles, if there were in the market many others of the same general kind, would cause that one to be extensively used in preference to the others. By an enlargement of the total amount of decorative articles used and by a relative favoring of a particular one of them at the cost of others, the sale of that one would be doubly increased. Cheaper diamonds might mean an increased use of them without any large reduction in the use of other gems; but if many other gems happened to be available for the purposes subserved by the diamonds the use of these others would be curtailed and that of diamonds would be disproportionately increased.
_The Value of Goods as affected by the Existence of Castes._--One of the reasons why the market for jewels is thus elastic is the fact that they serve as badges of caste, as only something of large cost can do.
If, therefore, all gems were to become much cheaper, two things would happen: (1) relatively poor people would buy some of them--partly in lieu of imitations and of cheaper real jewels; and (2) rich people would have to buy more and costlier ones than were formerly needed, in order to retain their positions in the social gradations. This principle affects the consumption of a wide range of articles, the possession of which seems, outwardly at least, to stamp the owners as belonging in a certain stratum of society. It increases the demand for fine clothing, furnishings, and equipage, multiplies social functions, and induces partic.i.p.ation in all manner of costly diversions. The elasticity of the market for luxurious goods is, in general, greatly increased by the action of this motive. The cheapening of them causes them to be consumed by the lower cla.s.ses and renders the use of greater quant.i.ties or higher qualities of them a social necessity for the higher cla.s.ses.[1]
[1] It is also true that an entire variety of gems or other things of this genus might, by mere cheapness, be branded as too common to be used by the very wealthy, except for new and inferior modes of adornment.
We shall soon see that a reduction in the cost of any one article usually causes the use of it to trench on that of all manner of things which are on the margin of consumption and are not similarly cheapened.
_Changes of Cost of Different Goods Never Uniform._--The cost of all articles is never reduced at the same time, and it is impossible that all of them should remain in the same order of desirability in the estimation of purchasers. Many things, however, are often cheapened at the same time, though in different degrees. Whatever furnishes a very common raw material at a lower cost than has prevailed, as did the invention of the Bessemer process of steel making, makes everything into which that material enters cheaper. By reducing the cost of railroads and engines, cars and steamships, the Bessemer process indirectly lowered the prices of goods that have to be carried, which means practically everything. A cheap motive power acts in the same way and lowers the costs of producing an unlimited number of goods.
Even in the case of such general improvements as this the reductions of price are not uniform. Some goods are affected more than others.
Cheap steel lessens the cost of bridges more than it does that of dwelling houses, and in the case of many improvements the effect is confined to a limited cla.s.s of products, if not to a single one.
_How the Disturbing Effect of a Single Improvement is Limited._--In the case of consumers" goods improvements are going on so nearly incessantly and at so many points that the effect is much the same as if every invention cheapened most of them at once. Harmful disturbances are reduced to minute dimensions by the multiplying of the changes, each of which, if it occurred alone, would produce a hurtful effect. Many inventions cancel one another"s unfavorable effects in a way that we shall later examine. What we now have to do is to isolate a single productive change and see whether there are forces working to reduce its own independent power to create incidental disturbance. What limits the power of a single new and economical process to eject laborers from their accustomed places of employment? This question cannot here be answered in detail, but a brief statement will cover the general principles involved. Obviously the displacement varies inversely with the extent to which increased cheapness enlarges the consumption of the article affected. If by making one thousand men produce as much of the commodity as two thousand formerly produced, you so reduce costs as to double the consumption of the article, you keep all the men who formerly made it in their accustomed places of employment. The elasticity of the want itself to which the article caters is one of the two elements that determine the increase in the consumption of it; but when this increase is due to an extensive subst.i.tution of this article for others in the purchasing lists of the consuming public, the result is greatly to reduce the displacement of labor which the new and economical method of production entails. Such subst.i.tutions are very general and are a large factor in rescuing men from the hardship of being forced out of the employments they are used to.
_On what an Enlarging Market for Tools and Raw Materials Depends._--The market for raw materials and tools depends on that for consumers" goods in their completed state. If _A_, the raw material, _enters only into A"""_, it can be sold in increasing quant.i.ties only as _A"""_ is thus sold. The chief fact about tools and materials is that they may contribute to a large number of completed goods, and the significance of this fact we shall soon see. The ultimate power to find a market for all products of the lower subgroups depends on finding one for the products of the uppermost ones--the _A"""_, _B"""_, and _C"""_ of our table. The laws which govern the market for finished goods of declining cost have first to be studied.
_The Effect of Subst.i.tuting one Consumers" Good for Others._--Reducing the cost of everything would cause an absolute increase in the consumption of everything; but reducing the cost of a single thing always causes, as we have seen, a _relative_ increase in the consumption of that one product. While the demand for other articles may not grow absolutely less, it becomes relatively less because of the comparative cheapness of the one product.[2]
[2] It is worth noticing (1) that uniformly reducing the cost of everything would cause _comparative_ changes in consumption. Anything which should take away a quarter of the cost of every article in the entire list of social products would increase the consumption of some articles more than it would increase that of others. There is an extremely theoretical case in which there might even be a lessening of the effectual demand for a few things because a uniform reduction of twenty-five per cent would cause other things to be extensively subst.i.tuted for them. This thinkable possibility is not practically important.
A detailed study would show (2) that a reduction in the cost of any single article in the entire list of social products causes an increase in the consumption of commodities in general. As an isolated man who has had to work hard for mere food and content himself with a few comforts and no luxuries will indulge in luxuries when food production becomes much easier, so society as an organic whole will increase its indulgences all along the line whenever the work of getting any one thing is reduced and some working time is thus liberated.
A subst.i.tution of one article for another in the lists of goods used by the public is a universal phenomenon attending an improvement which affects the production of one article only. When the cost of _A"""_ causes it to stand just outside of the purchase limit of a large cla.s.s of persons, a moderate reduction in the cost of it will make it a more desirable subject of purchase than the articles which have stood just within that limit, and it will be bought instead of one or more of these things. The securing of new customers for a finished product by means of a fall in the price of it is largely brought about by such subst.i.tutions. When the new article is added to a consumer"s list, the one which has stood as his marginal or least desirable purchase is taken off from it. It is the _relative_ desirability of buying one or the other of these articles that influences a buyer in his decision between them, and that cannot fail to be changed by anything that lowers the cost of one, leaving that of the other unchanged.
If the cost of a unit of each of ten articles be represented by the lines falling from the letters _A_, _B_, _C_, etc., to the base of the figure, a considerable fall in the cost of _A_ would put it below the cost of each of the other articles represented. If in the case of a large cla.s.s of persons who did not formerly buy any of the _A_ it is as desirable as any of these goods, it will take its place as the most desirable subject of purchase instead of the least desirable.
Those whose available means enabled them to acquire all the articles from _J_ to _B_ inclusive, but did not suffice for _A_, will now take the _A_ and omit the _B_. Those whose acquisitions stopped with _C_ will subst.i.tute _A_ for that article, and in general every buyer of any of these things who has not heretofore acquired _A_ will now put this in the place of the one which it was least worth while to acquire.
[Ill.u.s.tration]
_Subst.i.tutions caused by a Cheapening of one Utility in an Article which is a Composite of Several._--When different goods cost unlike amounts but are objects of equally strong desires, only one of them is a marginal purchase, and the others afford a personal gain to the consumer which is not offset by a cost. We have seen that this rule applies to the different utilities in a single good. In the case of every article several grades of which are sold, there is one component element or one utility which is worth to the buyer exactly what it costs, while the others afford a consumers" surplus. If the letters in the diagram represent, not whole articles, but utilities in articles, as discussed in Chapter VI, it will accurately express the essential facts. In such cases, which are very numerous, it is only necessary to reduce the price of the one utility which is now just worth its cost in order to induce more consumers to buy the grade containing this utility, instead of a lower grade of the same thing. In doing this, they forego the purchase of something else altogether, or content themselves with a lower grade of that other commodity. If jeweled watch cases should become cheaper, some persons would subst.i.tute them for plain cases and would forego buying, say, pictures which were just within their purchase limit, or would content themselves with cheaper pictures. This taking of one thing within the margin of consumption and discarding others is far less frequently done than is the taking of a lower grade of one kind of goods for the sake of securing a higher grade of another.
_Why Subst.i.tutions reduce the Displacements of Labor._--The question will, indeed, arise why the burden caused by the change may not be merely transferred to men in industries the products of which are displaced by the subst.i.tution. Something of this kind would occur if, in consequence of the cheapening of one article, any one other were generally discarded. The important fact is that it is not any one thing, but a wide range of things which are consumed in smaller quant.i.ties in consequence of the change; and the effect on the makers of any one of them is small. If a thousand men begin to buy the _A"""_ of the table we have frequently used, some of them will forego _B"""_, some _C"""_, and so on through the list; and the market for no one of these things will be much affected. Moreover, the nearly universal fact is that a man who begins to buy one article that he never before used will save the price of it by contenting himself with a slightly cheaper quality of a number of others. He will give up a dozen utilities in as many entire commodities in order to be able to buy the one entire commodity that he adds to his purchasing list. The reduction of demand is so extensively subdivided that it causes relatively few displacements of labor.
_Subst.i.tution a Prominent Cause of Varying Sales of Goods._--Subst.i.tution is, then, the general rule whenever the cheapening of a commodity wins new purchasers of it. This practice is not indeed universal in the case of those who formerly consumed these goods. Former purchasers of an article which has become cheaper may make no change except to buy more of it or a better quality of it for the same amount which they have been accustomed to spend for the inferior quality. They are not then obliged to economize in any other direction, and the change does not trench on their consumption of other goods. On the other hand, it is sometimes the case that they continue to use the original amount of the article that has become cheaper and use the liberated means of purchase--the "money," as it would ordinarily be termed--in buying other goods. The cheapening of _A"""_ thus even enlarges the demand for _B"""_, _C"""_, etc. There are thus two cases in which a reduction in the cost of one thing would not decrease the use of other things.
_Subst.i.tution More General in the Case of New Consumers._--The subst.i.tution of a cheapened article for others is the dominant fact in the case of new consumers of such an article, while an increased consumption of other things sometimes occurs in the case of old consumers. This does not have as large commercial effects as the other change. If we produce cheaper shoes, we make it easier to acquire good ones, and those who formerly contented themselves with an inferior kind take a better one. That means that they add to their purchase lists the higher utility which is present in the one grade and absent in the other. They buy a new element in goods rather than more of those goods, and while they may not always change their consumption of articles of other kinds they more frequently do so.
Those who begin to use something which formerly they went without altogether usually give up the use of some good or some quality in it, or get on with a smaller quant.i.ty of it in order to make the new indulgence practicable. The man who, when bicycles became cheap, bought the first one he ever owned probably gave up some other gratification.
_How the Sale of Goods which wear out in the Using increases as the Price Falls._--When goods deteriorate as they grow older, users have to buy new ones often if they are not willing to use those which are worn out and inferior. If we want always to wear clothes of good quality, we refrain from wearing a suit too long. We discard many things when they have somewhat deteriorated, and this forces us to buy, in a term of years, a larger number of them than we should otherwise do. We discard carpets and upholstery early when they are so cheap that we can afford to do so. We thus improve our goods qualitatively by adding to them quant.i.tatively.
_Subst.i.tutions a Protection for Labor against Undue Displacements._--Now, not only are the subst.i.tutions we have cited of commercial importance, but they act in the direction of retaining labor in a group where "labor saving" has been effected. They help to prevent this process from being equivalent to labor expelling in so far as either a general group or a subgroup is concerned, since they increase the social demand for the products of the group in question and cause a relative diminution of the demand for other things. Quite evidently there is, for these reasons, the more need for labor within this group and less need of it elsewhere. Cheap shoes may thus never mean fewer shoemakers and cheap watches may not ever mean fewer watchmakers.
_Subst.i.tutions of One Capital Good for Others._--It is not merely in the realm of consumption that the demand for a particular good may increase greatly in consequence of cheapness. The same thing happens in the realm of production, but here the subst.i.tution of one thing for others is an even more prominent cause of the increased use of the particular commodity. Aluminum and copper are rivals as carriers of electrical power, with the advantage at present somewhat in favor of copper. As soon as the cost of making aluminum shall be reduced by a moderate fraction it will become the cheaper material for such uses and, unless there is a fall in the price of copper, will thrust itself into use for trolley wires and other conductors of electricity. The possession of an enormous market by the one or the other material depends on their relative costs, and these may easily so change as to transfer most of the demand from the one material to the other. A further fall in the cost of aluminum would make it available for sheathing the hulls of ships and would bring it into general use for many household implements, while a sufficient fall would make it a leading building material and give it a limitless market for the framing and finishing of substantial structures. In these various uses it would subst.i.tute itself, not only for copper, but for steel, stone, wood and other materials, and the change would be extensive enough to give it an enormous market without requiring a correspondingly great reduction in its cost. Lowering the cost of aluminum by a third might, by merely making it the favorite carrier of electricity, multiply the present use of it by ten, and lowering it by two thirds might multiply the present use of it by a hundred. If this should take place, saving labor would be anything rather than expelling it from its position in the aluminum-making group. When less labor came to be needed for making a ton of the metal, more labor would be used in the industry that makes it.
So long as the subst.i.tution caused by the cheapening of aluminum affected copper only it might be a serious matter for the producers of copper; but when it came to replacing in some degree steel, stone, brick, wood, and other materials, the effect would be so diffused and subdivided as to create small disturbances in any one of these industries.
_Effects of Reduced Cost of Materials which already enter into Many Finished Products._--In the case of aluminum the prospect of a greatly increased market brings with it the probability that it may come to be a component element of products into which it does not at present to a great extent enter. Such things as steel, stone, and wood already const.i.tute important components of more articles than can be counted, and there is no great prospect that they will enter into a much greater variety of products. In the case of these materials there is a prospect that cheapness will show itself in reduced costs of the finished goods that are made of them, and that these finished goods will be used in greater quant.i.ties without subst.i.tuting themselves for other things in so drastic a way as that which we have described in the case of aluminum. A reduction in the cost of steel would indeed bring about a subst.i.tution of that material for others at every point where the steel and something else are now on a plane in desirability.
The type of building that now is made with plain brick walls and wooden floors, because that cheap mode of building enables it to earn a slightly larger interest on its cost, would often be made with a steel frame and concrete floors. At every such marginal point steel would gain somewhat on its rivals in the extent to which it would be used; but in addition to this enlargement of the market for it by subst.i.tution, one might count on an increase in the use of it because of an increase in the use of very many things that are already made of it. Some of these cater to highly elastic wants, and persons who use a quant.i.ty of them may be induced to use more without discarding anything else. Such an absolute enlargement of consumption is highly probable in the case of any material that enters into a vast number of products, and this, together with the enlargements that come by subst.i.tution, may suffice to create a great demand for the raw material and call for as much labor in the subgroup that makes it as was used before the improvement was made. In the case of the raw materials of industry the resources for gaining an increased market by subst.i.tution are:--
