There are only two plausible explanations for the average black kid with parental income exceeding $200,000 having the same SAT score as the average white kid with parental income below $20,000. Either:
(1) A group genetic disadvantage, and/or
(2) a *huge* failure of culture.
"Systemic oppression" doesn't cut it as an explanation because odds are high that the black kid attended good schools, had a relatively stable home life, and benefitted from good prenatal care. The well-below-poverty-line white kid would almost certainly have had little of those.
The only remaining explanation that the left has at its disposal is stereotype threat. But support for that theory in larger more rigorous studies is almost non-existent.
So what you have left are the third rail theories of genes and culture.
The table above used College Board data from 2008, but one would expect roughly the same results today because the black-white SAT gap has only closed a small amount since then. (Largely because the College Board made it less a test of intelligence.)

The SAT used to be more g-loaded — that is, a better test of general intelligence (more like an IQ test) — than it is now, but under pressure to improve black performance on the exam, the College Board reduced g-loading.
Score gap between the poorest whites and the second-wealthiest decile of blacks (which won't contain highly-paid athletes and entertainers) is even greater.
Also, most blacks in the top decile are not connected to the sports or entertainment industries.
A clear majority of researchers believe that genetic differences account for at least some of the US black-white IQ gap, according to a survey published in the scientific journal Intelligence in 2020. (See next tweet in thread for graph and link.)
