And it seems I need to spell it out for you, right there in the US during the same times, children of black people in the south didn't get access to education[1]. Serfdom was a thing in Europe until the early 1900, serfs children didn't get access to proper education[2]. I'm giving you a link to Russian education, but the whole of Eastern Europe was at a similar level. I don't know what kind of rose tinted cool aid you guys have been drinking.

Places like the South that didn't want to do that found themselves on the receiving end of losing a war, and now it's universal across all of America.
