Hey FDR type policies worked incredibly well in the crash of the early '20s as you very well know! Brought that crash right out it did, it did!
Oh, wait...
There were no "FDR type" policies in the early '20s unless you define the term so broadly as to make it meaningless. E.g., the Smoot-Hawley Tariff Act (1) was not an "FDR type" policy and (2) did not cause the Depression, though some crackpots say it did.
