How did the South and West change by 1900?

The South became powerful and rich. And the west became poor, so its population migrate to other regions surching for opportunities and better life.

Explanation:

The west resembled south where agricultural resources were concentrated in the hands of a few 1890 farmers. The poor farmers from the West joined with tenant farmers in south to support the people's party, sought to rest control of the political and economic system from the powerful east and return it to the plan folk. This contest would dominate the nation's politics in 1890's to set course for 20 century.

The South diversed his economy with more industrialization, more vocational training, and white supremacy social relations. The cotton industry grew bigger than New England's, iron manufacturing increased and American Tobacco Company became de most important industry in America for cigarettes. The agriculture and cotton were still relevant for the american economy.
