Even apart from your examples, (you missed Japanese interment camps/stolen wealth, probably the worst thing the US did domestically in the 20th century) racial profiling is still extremely real in this country. Which is on everyone radar, but it's really put into focus the times I've traveled cross country and consistently see POC on the side of the interstate.

I mean, the way I see it, explicit financial discrimination is still happening today. Its just called affirmative action.
