It's like we learned nothing from the 20th century: every time the rich get too greedy, they'll gleefully fertilize the fields of fascism before they'll accept making less money.
The rich wrote the history books and have a strong influence in education, so... yeah.
Don't forget about the Red Scare either. We're still feeling the effects today (mostly in the US, which matters everywhere else as well due to the economic influence of the US in the world)
