As a result of increased modernization in the late 19th century, this view changed in the emergence of the Progressive Movement, which held that the government can and should have a greater role in regulating the economy, so as to promote a better life for all of its citizens. The biggest change came with President Franklin Delano Roosevelt's New Deal, during which time the American government intervened extensively in the economy, guided often by Keynesian economics. New programs included relief for the poor, unemployed, and those who cannot work due to youth, old age, or disability.
