That's the key, right? You've gotta build a society afterwards that doesn't perpetuate the cycles of abuse and enlightens people with education. One that doesn't exploit anybody and doesn't have a class structure that divides people. That's the only way you can build a society that can reliably raise every child healthily. Any society that strives for equality like that will necessarily have to ignore the voices of those who want to hold it back.

There's ample of evidence that a couple of decades to reeducate their children and grandchildren simply isn't enough or doesn't work.

We had a couple of decades to educate everyone about fascism,... and yet we're here.
