FDR’s stated New Deal purpose was to keep work weeks short and to extend minimum wages which were extremely high. But, production is what makes demand possible and what increases purchasing power, not federal mandates.
FDR’s policies created ceaseless tax increases, suffocating regulations and inane projects like slaughtering animals and destroying crops. WPA money seemed to be spread in areas for political reasons of getting electoral votes. The West got considerably more money. In 1937 FDR schemes to pack the Supreme Court were presented as ways to help the Court. This Court later said that a farmer growing wheat on his own property for his own consumption was part of interstate commerce and subject to federal regulation.
The biggest myth is that an economy is helped by war. Did war end the Great Depression? No. War lends a stimulus to certain sectors of the economy, but it is overall destructive of things that are not seen and things that are lost opportunities to civilian producers.
