Well when the education system of the US essentially teaches:

• Nazi bad because they hated Jews. That’s it. Don’t look at why they chose Jews as a target to scapegoat societies material problems. Don’t look at how closely connected fascism is to the interests of capital. And definitely equate them with socialism because they had that word in their name. Ignore the fact they put Marxist in concentration camps first.

And then teach:

• Stalin bad because he was a “authoritarian” and purposely starved his people while eating all the wheat with a big spoon. This is all that socialism ever is. It’s just when one guy has all the power. Don’t look up what “Soviets” actually were. Definitely don’t teach about the country that was most responsible for stopping and defeating the Nazis. It was all just our big bomb we dropped on a completely different country that was entirely needed and not an unnecessary show of force to the USSR.

Its easy to manipulate “educated” people to working against their own interests.
