I certainly didn't mean it as a "thinly veiled attack on minorities," and it does seem more likely linked to the economic history of various communities. Children of college graduates are more likely to go to college themselves; parents with PhDs are more likely to have children who receive them as well. That could be due to genetics or shared environment or other factors, and there's a whole realm of twin and adoption studies on how much life outcomes are due to shared environment versus inheritance. Bryan Caplan has a good summary of this in the book Selfish Reasons to Have More Kids (p. 53-58), but it mostly favors the inheritance-based view over the cultural one (admittedly contradicting my original assertion), and so certainly isn't going to be more friendly towards your view of trends in generational wealth. How the suggestion that some social environments will be more supportive of self-education than others automatically becomes an attack on minorities is baffling. There was no intended suggestion of any such thing, and the entire rest of my post was hypothesizing something completely different: society's increasing net productivity leads to increasing gaps in income.
