I think you need to source the claim "There is no educational / societal intervention that can reverse its impact on Black kids' education" Consider, just as one example, the paper "Are High-Quality Schools Enough to Increase Achievement Among the Poor? Evidence from the Harlem Children’s Zone" (Dobbie and Fryer 2011)
https://scholar.harvard.edu/fryer/publications/are-high-qual... Here is the abstract: "Harlem Children’s Zone (HCZ), an ambitious social experiment, combines community programs with charter schools. We provide the first empirical test of the causal impact of HCZ charters on educational outcomes. Both lottery and instrumental variable identification strategies suggest that the effects of attending an HCZ middle school are enough to close the black-white achievement gap in mathematics. The effects in elementary school are large enough to close the racial achievement gap in both mathematics and ELA. We conclude with evidence that suggests high-quality schools are enough to significantly increase academic achievement among the poor. Community programs appear neither necessary nor sufficient." |

On the contrary, if you search through education literature, you will see countless successful programs, but why don't we see their effects at the societal level? Because it almost never scale. Education program is not something you can duplicate easily, it is almost always extremely localized.
In education, it is very difficult for a successful experiment / program to scale vertically (expand to all grade levels) or horizontally (expand to other schools, districts). Also treatment effects are difficult to retain after students left the program, or after the experiment ended.
Interestingly, Taleb just made a twitter this morning: "What works on a small scale almost NEVER expands to large scale." https://twitter.com/nntaleb/status/1035121052886728704
