So what?
You seem to be assuming that Black people simply have more skill and performance than others. You do this in Basketball but not in other areas.
Currently, hiring males for programming jobs is due to skill and performance, because far more men chose to go through this type of education than women. Huge numbers of men and women don't enjoy straining to grapple with abstract concepts for long stretches of time, sitting hunched over a keyboard, and so on. But, more men do than women, at the moment. So does that mean things are just fine the way they are, as your comment suggests about being Black and skill and performance?
Why not encourage, for instance, more Chinese basketball players to get scholarships, and increase their skill and performance? Why settle for how things are, which currently is not very diverse as anyone can plainly see?
China's basketball team has a lot of great Chinese players.
