I don't disagree with the premise (that African American's are under-represented at the University level), but I don't think it's on the face true that having a DEI program is a requirement to get there. No one will say this out-loud today, despite the hostile environment for it, but about ten years ago I was told (by a dean, no less) that the Division of Diversity and Community Engagement was a Bill Powers/Dr. Vincent project and it was mostly just for show. I'm sure it's had a chance to evolve in the interim, but a program with 350 staff members seems like a lot bureaucratic bloat.
From a public policy perspective, we'd probably be better off taking that same head count and creating an enrichment coordinator or guidance counselor at the 350 high schools with the greatest proportion of African Americans with the main job of pushing average or slightly better achievers towards college*. That's likely where you could do the most good. I'm sure they/you might not feel this way, but to some degree the African American scholars at UT are closer to the "haves", in that most have been admitted because of their grades and test scores, which is a product of good study habits, raw intellect, support at home, school quality, etc.
*yes, I know the state government is not making that choice.
If you study the history of the US' world renowned higher ed, it's mostly a story of federal research dollars flowing into them.
