Affirmative action in education benefits wealthy black and Hispanics at the expense of poor whites and Asians.
I've had a few conversations about the subject recently where that didn't seem to be intuitive to the people I was talking with so it's worth stating explicitly here even though it's hardly a novel observation on my part.
For simplification, just think about whites and blacks. In both cases, the wealthier a person (or the family he grows up in) is, the better his academic performance tends to be. Whites outperform blacks at every level of socio-economic status (SES), but in the cases of both whites and blacks as SES increases so does academic performance.
So if some number of whites who would otherwise be accepted to a school have to be cut out to make room for a corresponding number of blacks, it tends to be low SES whites who get the cutting. The blacks who get in are those who (relatively) narrowly missed getting in before the racial handicapping. These tend to be high SES blacks.
In the subsequent graph, it's the area inside the red circle that gets cut out by affirmative action and the area inside the green circle that benefits from it:
Comprehending this dynamic would go a long way in helping affluent SWPLs who still don't understand Trump's appeal to working-class whites understand that appeal better.
We continue to have an opportunity with frustrated Bernie Bro-types who keep getting spit on by the Democrat party, most recently with the victory of Perez over Ellison as DNC chair. Sanders started out his campaign shying away from race and making it about social class disparities. He was forced into racial grievance mongering and victimization posturing by the Clinton campaign, but he didn't want to go there initially.
This isn't a novel observation on my part, either. Trump certainly gets it:
