I think you're confounding competence and skill levels with "smarts". I wouldn't argue that the output of elite schools is not measurably different than that of e.g. state schools, but I think your view that the intrinsic quality (e.g. IQ) of the people is different is mistaken and not backed by any evidence.

Tangentially, I think it is lazy to say somebody who is disagreeing with you is just being "politically correct" or "a product of the present moment". I see no evidence for claims like yours, which strike me as more ideologically driven than you might believe.
