I think I understated the advantage the wealthy have while making the point that the parent comment had overstated it. That said, I'm embarrassed to admit my opinion was mostly informed by anecdotal evidence, and your example with Harvard is certainly better than that. The "fact sheet" in the article is dead, but the conclusion seems reasonable. I'd hoped my comment might serve as some encouragement of the sort outreach might, not as a justification for the current state of economic diversity at elite schools.
