Final answer:
President Roosevelt's philosophy during the Great Depression focused on expanding the role of the federal government to actively intervene in the economy through his New Deal programs. These measures included relief, regulation, and infrastructure projects to revive the economy and support those in need.
Step-by-step explanation:
During the Great Depression, President Franklin D. Roosevelt (FDR) embraced a philosophy of active government intervention in the economy. Unlike his predecessor, President Hoover, who believed in a limited government approach and voluntary business measures to address the economic crisis, Roosevelt advocated for a significant expansion of federal power to provide relief to the American people. This philosophy is evident in his New Deal programs, which included federal relief, public works, social security, unemployment insurance, regulation of the economy, and direct assistance to farmers. These measures were designed to restore public confidence, help prevent future economic downturns, and stimulate economic recovery.
