I generally agree with your post—but black intelligence is on a normal curve and (imho) it is only the top tenth or at most top fifth of that curve that can truly benefit from higher education.
That said—everyone benefits from rigorous educational standards—and failure if they cannot meet standards.
No public or education official has the courage to deliver the bad news.
Oh I agree that people of all ethnicities are allowed into college that have no business being there. That’s a separate discussion.
The problem is the liberal lowering of standards hurts the top achievers of all races. Nobody resented “the smart kid classes”. It was just a fact of life. Teachers knew it was important to keep kids minds challenged. My brother was a mathematical genius who used to be a member of a gang (1950s, duck tail hair cut, lucky strike pack rolled into his sleeve) but he had a teacher who challenged him to the point where he had professors at ASU helping to come up with problems for him to solve.
Standards need to be raised not lowered, kids need to be challenged and careers other than those requiring a college degree need to be offered.
