One would hope that if admittence into these schools is truly based on merit, then they'd pick the best regardless. I mean, what if Inuits turned out to be the most gifted genotype of humans WRT intelligence. Would it be wrong if Harvard became 80% Inuit? Presumably the student body would be smart enough to retain the culture that works and dump the stuff that doesn't, at a relatively conservative rate. (Personally I think elitism itself is what these institutions are defining/producing/protecting, and math ability is (relatively) easy to measure. I personally would love it if MIT started feeding us Presidents and Senators instead of Harvard -- or maybe better, if Harvard really kicked people out for failing to learn calc by second year.)
