I'm very interested in the Great Depression. I'm surprised to learn that there were conditions of extreme poverty in the Southern United States, with massive migrations to California and even that deaths by malnutrition were not rare. I think those were very good conditions for fascism to rise and take over the country, just as it happened in similarly impoverished Germany and Italy. I've read that movements defending fascist-like opinions did exist in the US, and that some leaders were in favor of a populist turn for the country. I really can't understand how did the US manage to keep its democracy intact and even stronger, given how easy would it have been (looking with today's eyes) to exploit the anger and the suffering of the poor and lead them into a totalitarian nazi-like regime, like it happened in Germany. Thank you.
I highly recommend you read the book Hitler in Los Angeles by Steven Ross. Although it mainly focuses on LA (really California) it does detail many of the fascist coup attempts in various cities. It will help answer your question.
