Elite blacks definitely step in and educate their own, and at a very high level of commitment and thought.
But I know thats not your question. I am responding at the family level, but you were asking in general.
The general side of it will take maybe two generations for it to happen (at a broader more diffuse level). Why? Its a complicated answer, but the Cliff Notes version is that most elite blacks (and I am talking Africans not your home grown American cousin) are almost to a man just one generation removed from poverty. Thus, there is a tendency to keep things close to the family and ensure the family is the key focus, and thus theres a sort of convex lens that concentrates matters at the family level (and interestingly, this also explains some of the stupid corruption one sees - similar to how a village dog will snatch a piece of meat that falls from the table, while a little cute Pommy in the South of France will look with disdain at a juicy morsel of meat ...and it is something that is also seen, at different concentration levels, amongst the elite in Asia and Latin America).
There are exceptions - as far back as the late 50s and early 60s, a Kenyan called Tom Mboya working together with (then Senator) JFK airlifted many Kenyans to leading American universities for their tertiary education. But then again, this was still at a family level - with family being the two leading communities then in Kenya. As an aside, maybe you should be careful what you wish for since an (indirect) beneficiary of that was a certain gent by the name Barack Obama Snr who met a nice American lady and had a healthy bouncing boy called Barry ...(I need a glass of water to wash down something that came up my throat).
Anyway, it happens - just not on a broader help everyone level, and it will take maybe another generation or two to get there.
Please also note I am talking about educated upper crust Africans. Theres a lot of survivorship bias, but several studies have shown that educated Africans in the West have more in common with Asian immigrants (in terms of not just education but professions and income) than with your African Americans, and I am absolutely not qualified to discuss AAs. Im sure you also know theres not a lot of love lost
Understood. ..

And that “education” sure didn’t do much to help Barack O. Sr, nor Kenya, now did it?!
