AA is a societal remedy to a societal-level injustice. Redlining and biased admissions policies only looked at the color of one’s skin too.
Obama talked about this at length; regardless of his family past he also suffered racism, whether it was trying to get a taxi or how people treated him in the workplace.
Less educated parents creates a cycle of poverty, which is one of the reasons AA is used as a remedy to address the fact that white Americans were given more opportunities including scholarships and housing benefits that were denied to POC.
AA shouldn’t be permanent but we are not past the injustices yet.
