The Gilded Age saw immense industrial growth fueled by new technologies, abundant resources, and massive immigration. This led to huge fortunes for industrialists but also harsh working conditions and inequality. As cities grew rapidly, political machines consolidated power while corruption and poor living standards plagued urban immigrants and workers. On farms, overproduction caused economic hardship. The post-Civil War South saw some economic development but blacks faced increasing segregation and loss of civil rights under Jim Crow. Responses to these challenges included labor organizing, populism, and differing philosophies within the black community.
