There is definitely correlation between race and academic performance in America, but there is no reason to think there is causation, or much causation. What little causation exists would be hard to tease out and is likely because of immigration selection. An Asian who comes to America likely is here because they out-competed their peers to make it here. My customers are almost completely immigrants from China and India and are mostly in tech. They are largely smart people who did well back home and do even better here. Their kids, on average, perform well too, but in addition to coming from the parents who could get through all the selection processes to get and stay in the US, they also have access to great schools, great nutrition, tons of extracurricular activities, and good genes for their races. If I go to India or China, I'm going to find a far dumber distribution of people, and even then, most of that will be because of economic circumstances, not genetics. The genetic component, of the US grabbing mostly the cream, lowers the average intelligence of these countries by a vanishingly negligible amount.
A child with genius genetics who is raised by wolves will effectively be a moron. A sub-100 IQ person who receives immense resources can graduate college. When I was done with him, a low-IQ autistic kid I taught, fully verbal but pretty damn simple, passed his college English classes and wrote proper, passing rhetorical analysis essays for exams without help. It took years of work, from late middle school on, but he got there. Both his mom and dad have PhDs. He reads at at least an average level for American adults, which is not that impressive in general but is for him.
