In the field of production the most dramatic and striking advances have been achieved. The application of steam and more recently of electricity as the motive power for the newly invented and constantly improved machinery has permitted an enormous expansion of production, which has been made still greater by the opening up of new mines and new lands and improvements in the machinery of transportation and exchange and in the organization of business. Especially in the United States where the natural resources were especially rich and the people energetic and ingenious, has the growth of wealth been marvelous. And yet almost a century after the beginning of the Industrial Revolution in England, Mill alleged that labor-saving inventions had not lightened the toil of any human being; they have only enabled a greater number to live the same life of drudgery and imprisonment. What answer can we make to this indictment today? Why is it that the working class still has so little of this vast increase of wealth and still lives so close to the border line of poverty?
To answer this question thoroughly would require an analysis of the subject of distribution, but a few reasons may be briefly suggested.[51] While the social income has been greatly increased by these improvements the amount paid in rent to owners of land, water powers, etc., has also grown. If we approve of private property in land as best adapted to stimulate its use for society, then we must admit the justice of rent, and of its payment to present land owners. Similarly, too, the payment of interest to the owners of capital has absorbed a large part of the increased income of society, though the proportion going to this factor is probably growing smaller owing to the fall in the rate of interest. But as we have seen, modern industry is essentially capitalistic, that is, it depends upon the use of 175 capital for its operations. Since we allow private property in capital and believe that to be the best method yet devised for securing its accumulation, we must justify interest. Profits in general are fairly earned by industrial organizers and others who manage our businesses, and are necessary to enlist their services. Probably in most cases society does not overpay these leaders of industry. But some forms of profit, as those derived solely from monopoly, especially from the monopoly of limited natural resources, are both too large and socially unearned. These society should clearly control and absorb.
