There was only one Hoover idea that Roosevelt enacted (Hoover was too chicken), and that was Roosevelt's Banking Act in the first few months of his administration.Originally Posted by Praxus
How did Roosevelt prolong the Depression? The US economy had returned to 1928 levels by the end of his first administration. Roosevelt backed off on the New Deal in 1937 (with some help fromf the Supreme Court, which declared many of his programs unconstitutional), and the economy went into temporary recession in 1938. Roosevelt's second New Deal, in 1938, was followed by an expansion until 1940. After that, the buildup to WWII took over.
