On Malcolm Gladwell's podcast Revisionist History, he talks about Brown v BoE, and what's interesting is that the opinion from the SCOTUS was that "children should have equal access to quality education no matter their skin color". The argument was that black run schools were worse because "black teachers were naturally worse than white teachers". The result was that when schools were integrated, the black teachers were disproportionately let go and the schools kept all the white teachers.

This is a big reason black students didn't receive the support they needed as they had to deal with teachers who were now biased against them.
