Which president is noted for initiating numerous welfare programs and significantly increasing federal funding?

Franklin D. Roosevelt is noted for initiating numerous welfare programs and significantly increasing federal funding primarily through his New Deal policies during the Great Depression. His administration implemented a series of initiatives aimed at providing relief to the unemployed, economic recovery, and reforming the financial system. The New Deal included programs such as Social Security, the Civilian Conservation Corps, and the Works Progress Administration, which not only aimed to alleviate poverty but also focused on infrastructure development and job creation. These programs fundamentally changed the relationship between the federal government and American citizens, expanding the government's role in social welfare and laying the groundwork for future social safety nets.
