1. _In the discussion of the so-called trust problem three things must be distinguished: large individual capital, large production, and monopoly power._ Capital, in the sense of valuable agents, is found in the smallest as well as the largest industry, and every owner, from the small shop-keeper to the wealthiest bondholder, is a capitalist. In popular discussion, however, the word frequently implies great wealth in a single hand, though this wealth may be invested in a large number of small industries. Large production is the concentration of capital into large units of industry. The capital may be the same as before, the ownership may or may not be widely diffused, but the control and management are unified. Large factories may or may not have monopoly power; as factories grow in size, competition among them often becomes more, not less, complete and severe. On the contrary, monopoly, as before defined, may exist where the industry is small, as the waterworks in a small town, or a small factory for making patented articles. In periods of depression a business with a capital of ten thousand dollars may go on and prosper, while one with millions may be forced into bankruptcy. These three ideas--great individual wealth, large industry, and monopoly power--are often hopelessly confused in the discussion of present-day questions. [Sidenote: Stages of tools and household industries] [Sidenote: Of simple machines] [Sidenote: And of large industry] 2. _Three industrial stages may be broadly distinguished: that of tools, that of machines and small factories, and that of large production._ Men are prone to forget that all the world is not doing just as they are. Over two thirds of the people on the globe are still in the first industrial stage. One billion people use only tools, and have no better source and means of power than domestic animals. This is true in the most of Asia and Africa, in the greater part of South America, and in many portions of North America. About two hundred million people live in the stage of simple machines and small factories. These are found in eastern and southern Europe, small portions of South America, some parts even of the United States. In this stage there is not enough manufacturing power in the community to supply much more than its own needs. About two hundred million people in the United States and western Europe have reached the third and highest industrial plane, where the highest mechanical devices are employed and industry becomes highly specialized. These differences are broadly stated; there are contrasts within every nation. Three hundred miles from here, in the Alleghanies, people still can be found spinning and weaving and wearing homespun as in colonial days. In a trip of twenty miles in Tyrol or Switzerland one can observe every one of these industrial stages. The most striking development, if not the typical form, in America to-day is large or concentrated industry.
