From the late 1870s to the early 1900s, the United States underwent a dramatic transformation, driven by rapid industrialization and its economic, social and political effects.
As factories hummed with production and railroads stretched across the continent, the nation grew more prosperous than ever. But beneath the sparkling surface of the Gilded Age lay a more complicated reality. Amid such swift industrial growth, the nation’s wealthiest citizens enjoyed unprecedented prosperity even as working-class Americans suffered due to low wages, poor working conditions and inadequate or overcrowded housing. For every tycoon amassing massive wealth—like John D. Rockefeller, Andrew Carnegie and J.P. Morgan—there were countless laborers, immigrants and families struggling to survive.
“It is as though an immense wedge were being forced, not underneath society, but through society,” wrote reformer Henry George in his 1879 book Progress and Poverty. “Those who are above the point of separation are elevated, but those who are below are crushed down.”
