That's an uncharitable read of my comment. (Or more likely my comment was clear as mud.) As you said, the above theory was that the current wealth gap can be explained by generations of discrimination. But if another non-white group can enter at a similar "difficulty" level and attain higher results, maybe the explanation is more complicated. I think then the focus would need to be on current (possibly discriminatory) policies and factors, rather than historical ones. Education, family unit, cultural factors, etc.
