Race is not just a proxy for education. Racism affects Asian-Americans, despite their good educational track record as a broad group; African immigrants, despite the fact that Nigerian immigrants and Nigerian-Americans make up the immigrant group with the largest number of PhDs per capita in the US immigrant landscape; and British immigrants, who everyone thinks are smart because of the accent (despite no better educational attainment than anyone else).
The real injustice is that my black students cannot earn or learn their way out of being black in America. A Caltech education doesn't help when you're pulled over by the cops. This blogger's ability to use "Hence" in a literature review won't help either.
