Just because the US keeps its population deeply uneducated doesn't mean it isn't also working extremely hard to keep it propagandized and placated in ways that uneducated historic revolutionary populations were not. The material conditions in the US right now are still vastly different than those places as the very center of the imperial core. Illiteracy does not have to have a causal relationship with revolutionary potential, it's just that literacy is not required to have a revolutionary population. I think ExistentialNightmare is right, certainly in the short term, neither party, who both represent the ruling class, benefits from having an educated population. Long term is another story, but we all know that long term isn't a real consideration otherwise climate change would be taken seriously by the ruling class beyond using it cynically for fascist agendas.

Education is a useful tool for refuting propaganda. Today, we are saturated with 24/7 propaganda, so the masses need to be educated enough to read, but not enough to have critical thinking skills and tools for evaluating media.

It is precisely the rate at which bourgeois propaganda is created and adapted now that creates the conditions where more education is necessary to foment revolutionary sentiment. The means of publication and distribution today make relying on the manpower of a small, elite group of revolutionary vanguardists insufficient to debunk the garbage circulated by the press. The masses need to be capable of doing a portion of this on their own.

Americans are mis-educated, not uneducated.
