A People's History of the United States

In the year 1877, the signals were given for the rest of the century: the blacks would be put back; the strikes of white workers would not be tolerated; the industrial and political elites of North and South would take hold of the country and organize the greatest march of economic growth in human history. They would do it with the aid of, and at the expense of, black labor, white labor, Chinese labor, European immigrant labor, female labor, rewarding them differently by race, sex, national origin, and social class, in such a way as to create separate levels of oppression-a skillful terracing to stabilize the pyramid of wealth.

Between the Civil War and 1900, steam and electricity replaced human muscle, iron replaced wood, and steel replaced iron (before the Bessemer process, iron was hardened into steel at the rate of 3 to 5 tons a day; now the same amount could be processed in 15 minutes). Machines could now drive steel tools. Oil could lubricate machines and light homes, streets, factories. People and goods could move by railroad, propelled by steam along steel rails; by 1900 there were 193,000 miles of railroad. The telephone, the typewriter, and the adding machine speeded up the work of business.
