Under competition the process that, with a given amount of labor and capital, turns out a larger product inevitably displaces one that turns out less. The employer who is using the better method undersells those who use inferior ones, and forces them either to improve their own methods or to go out of business. Working humanity as a whole is therefore making a constant gain in producing power, as man's appliances equip him more and more effectively for his conflict with nature and enable him to subjugate it more rapidly and thoroughly. It would seem that they ought to have only good effects on wages, and in the long run they invariably do have such effects. In the absence of improvements there would be little hope for the future of wage earners. The immediate effects of improvements upon individual workers, as we shall see, are not always unqualifiedly good, but the essential effect is the general and permanent one, and the character of this has been attested by past experience too fully to be in doubt. In improvements in production lies the hope of laboring humanity. Nearly the whole earning power of the labor of the present day is the result of improvements that have taken place in the past, though these gains have not been secured without causing local and temporary hardships. If in the future the wages of labor are doubled or quadrupled, as the result of a series of improvements beginning now and extending to a remote period, this progress cannot be secured for nothing. The costs will be less than those attending improvements of the past, but they will be real. The most important fact is that they tend to become fewer and smaller and that the gains immeasurably exceed them. 4. _Changes in Organization._--There are changes in the mode of organizing the establishments in which commodities are produced, and so far as these occur under a regime of active competition, they also are improvements and give added power of production. The mills and shops become larger and relatively fewer. There is a great centralizing movement going on, since the large shop undersells and suppresses the smaller one, and combinations unite many great shops under one management. The effect of this, when it takes place in a perfectly normal way, is akin to that of improvements of method. It benefits society as a whole somewhat at the cost of individual members of the body, and it causes wages to rise by adding continually to the wealth-creating power of the men who earn them. We shall see that when consolidations repress competition their effect is far from being thus wholly beneficial, and that not only are particular persons injured by them, but the community as a whole has a serious bill of charges to bring against them. The securing of the gains that come by consolidation without such evils is an end the realization of which will tax the statesmanship of the future.
