The rise of industrial capitalism in the U.S. from 1870-1920 was not due to a free market, but significant government intervention. The government subsidized railroads, passed laws allowing incorporation with limited liability, helped crush labor strikes, enacted high tariffs, and used the military to remove Native Americans from lands - all to encourage business growth. Industrialization transformed the economy, with manufacturing jobs rising from 29% to 44% of the workforce over this period. New technologies revolutionized industries like steel, oil, automobiles, and more. However, the myth that industries developed freely in a free market is untrue, as the government played a major role in stimulating industrial and economic development.
