Arguably, the US still has a system like this. Redlining didn't end until what, 1980ish?

Getting rid of the explicit, codified practices of discrimination doesn't remove the discrimination itself. And until we've paid back the damages to the families injured by practices like redlining, we've inflicted financial and social wounds across generations of people descended from those we harmed.

Go to the American military and look for the absence of upper class mannerisms common to any private college…

Go to prisons and look to see the ratio of minorities to white peoples, and look for what portion of people there grew up in poverty

Go to the wealthiest institutions in America and count on one hand the number of people there solely on their merit

Our society is no different than the caste discrimination we claim to abhor, just different superficial rhetoric on top.

Both these cultures need to be overthrown.
