Hoover was actually trying some of the same schemes that Roosevelt later implemented, but his name was mud by then, so it took a new guy to foist them on everybody.
I think Woodrow Wilson was the one who kicked off the progressive movement who followed the ideas of the British Fabian Socialists ....”Communism by evolution, not revolution”. Gobbels is supposed to have claimed he learned his propaganda techniques by studying Wilson’s press secretary.
And Hoover did the exact opposite of what his predecessor, Calvin Coolidge, did in the 1921 depression. Coolidge’s action made that one short.
