Either Harding or Coolidge, because they did the best at keeping the government’s hands off the free economy.
RE: Either Harding or Coolidge
Unfortunately, Harding’s administration was tainted by scandal and corruption (although his economic policies were correct. He got us out of what could have been a depression in 1920. Had FDR or Hoover been president then, the great depression would have started in 1920 ).
