The same aspect presented by the economic development of Germany is presented by all the industrial states of the world. All the civilized states endeavour to become industrial states more and more. They not only seek to manufacture articles of industry to supply their own demand, but also to export them. Therefore we not only speak of a national market, but also of the ~world market~. The world market regulates the prices of countless articles of industry and agriculture and controls the social status of the nations. That industrial realm which has attained the greatest importance in regard to the relations of the world market, is the North American Union. Here the main impetus is given whereby the world market and bourgeois society are revolutionized. The census of the last three decades showed the following figures: Amount of capital invested in industry. 1880 2,790,000,000 dollars 1890 6,525,000,000 “ 1900 9,813,000,000 “ Value of Industry. 1880 5,369,000,000 dollars 1890 9,372,000,000 “ 1900 13,000,000,000 “ The United States, accordingly, is the leading industrial country of the world. Its exportation of products of industry and agriculture increase with each year, and the tremendous accumulations of capital that are a natural result of this development seek investment beyond the boundaries of the country, and influence the industry and trade of Europe to a marked degree. It is no longer the individual capitalist who is the motive power underlying this development. It is the group of captains of industry, the trust, that is bound to crush the most powerful individual enterprise, wherever it chooses to turn its activities. What can the small man amount to in the face of such development, to which even the great must yield? [194] Otto Hué--History of the development of the mining industries. [195] A.

It is an economic law that, with the concentration of industry and its increased productivity, the number of workers employed relatively decreases, while the wealth of a nation, in proportion to the entire population, becomes concentrated in fewer hands. That can be clearly seen by the distribution of the income in various civilized countries.
