_How Displaced Labor is Replaced._--When men are actually forced to leave an industry,--say the subgroup _A'_,--they find themselves, in the search for employment, in the same position as a body of newly arrived immigrants in quest of work. Men of either class must offer themselves at a rate that will induce employers to take them. If much new capital has lately been created, it is naturally possible for the men to get employment without having to overcome serious friction or to reduce their demands in the way of pay. In the absence of such additions to the capital, they might possibly have to offer some inducement to employers, in order to overcome their reluctance to make changes in their shops. We shall see in due time, however, that where improvements are well distributed through the industrial society and have their natural effect, they tend to increase the general demand for labor at the original rate of pay. _Effects of a Series of Improvements confined to One Industry contrasted with those of Improvements diffused through the Groups._--A continuous series of radical improvements, all originating at one point, would tend of themselves to cause a series of expulsions of labor from that point, and the mere increase of population and wealth might not so fully counteract this tendency as to prevent a positive exodus of labor from the occupation affected. A merely relative reduction of labor in this occupation would not cause much hardship, since it would only mean that other industries were attracting the greater number of young laborers entering the field and gradually getting a larger and larger part of the whole working population. If men actually in _A'_ can stay there, no one is injured; but too great a concentration of improvements at this point might drive some of them away. Such concentration is the opposite of the general rule. Improvements do not confine themselves to one point or to a few points, but originate at very many, and this fact neutralizes their labor-expelling tendency and might reduce it practically to _nil_. If labor could be made more efficient in every group of the whole system, the result would be to increase the quantity of every kind of goods. Making more of one's own product is acquiring power to buy more of the products of others; and enlarging the general output of goods tends thus to increase the demand for all kinds of goods as well as the supply. If you make clothes and I provide food, and we exchange products, but do not satisfy each other's wants to the point of repletion, it is well for both of us that you should become able to make more clothes and I to furnish more food. We can then go on with our original occupations and both live better. In this there is involved no displacement of labor at all; and neither would there need to be any disturbance caused by multiplying in well-adjusted proportions the output of each group and subgroup in the system of industry.
