Whites were slaves to rich whites. Blacks and poorer whites were comrades many times throughout history, and have fought against rich white men together. Bacon's rebellion and many other instances in Virginia. But we focus on black slaves to create division early on in children.
Can you imagine the stark difference we'd see if children were taught this? Like, yeah whites enslaved blacks but most didn't own slaves. And whites were enslaved too. And guess what? Black and whites came together to fight back many many times.
That'd change everything. But of course they can't teach the kids that. The elites thrive off of division.
