The industrialization and gilded test:

From the 1870s to the 1890s, the United States entered a period of rapid industrialization. There was a shift from agriculture based economy to an industrial economy and many Americans began moving to urban areas.

Industrialization has greatly increased the need for workers in the country's factories. The availability of low or no skilled factory jobs is one reason why immigration to the United States has increased significantly. Although working conditions are poor and unsafe in most factories, there is a steady stream of migrant workers to replace positions.

In the Gilded Age, economic disparities between workers and big business owners have skyrocketed. Workers continue to endure low wages and dangerous working conditions for their livelihood. Big business owners, however, enjoy the luxurious lifestyle.
