What terms best describes the collection of social programs put together under President Franklin Roosevelt in the 1930s to lessen human misery and end the economic downturn called the Great Depressio?

Roosevelt called his plan the "New Deal".

Unfortunately, the "New Deal" programs failed utterly to improve the state of the American economy, and recent research has suggested that these were precisely the wrong nostrums. The New Deal programs stifled growth and retarded the economy, and magnified the impact of the Great Depression; this is a common result for government managed economic programs.

The economy didn't recover until a year after the start of World War II.
