Looking at this in terms of race is misguided. Don't do anything for "black people," just help "poor people" get better educations by giving more money to poor schools. A lot of "poor" schools are actually black schools, but not all, so more than just black people will benefit; and not all black people are poor, so we won't waste resources on those who already have them.
Defining DEI as "doing anything about the problem" and then saying that DEI opponents therefore don't want to do anything about the problem is a lazy bait-and-switch that I wish we would all recognize and stop doing.
