Answer:
The ideas of social Darwinism attracted little support among the mass of American industrial laborers. American workers toiled in difficult jobs for long hours and little pay. Mechanization and mass production threw skilled laborers into unskilled positions. Industrial work ebbed and flowed with the economy. The typical industrial laborer could expect to be unemployed one month out of the year. They labored sixty hours a week and could still expect their annual income to fall below the poverty line. Among the working poor, wives and children were forced into the labor market to compensate. Crowded cities, meanwhile, failed to accommodate growing urban populations and skyrocketing rents trapped families in crowded slums.
Strikes ruptured American industry throughout the late-nineteenth and early-twentieth centuries. Workers seeking higher wages, shorter hours, and safer working conditions had struck throughout the antebellum era, but organized unions were fleeting and transitory. The Civil War and Reconstruction seemed to briefly distract the nation from the plight of labor, but the end of the sectional crisis and the explosive growth of big business, unprecedented fortunes, and a vast industrial workforce in the last quarter of the nineteenth century sparked the rise of a vast American labor movement.
The failure of the Great Railroad Strike of 1877 convinced workers of the need to organize. Union memberships began to climb. The Knights of Labor enjoyed considerable success in the early 1880s, due in part to its efforts to unite skilled and unskilled workers. It welcomed all laborers, including women (the Knights only barred lawyers, bankers, and liquor dealers). By 1886, the Knights had over 700,000 members. The Knights envisioned a cooperative producer-centered society that rewarded labor, not capital, but, despite their sweeping vision, the Knights focused on practical gains that could be won through the organization of workers into local unions.
