Where do you draw the line? White Gentiles are the majority population of this country, yet dramatically underrepresented in the Ivy League. White Jewish students of comparable ability are roughly 1,000% more likely to be enrolled at Harvard and the rest of the Ivies.
Does their representation matter to you? How about South Asian students versus Chinese, or (perhaps most concerningly) wealthy Nigerian immigrants versus poorer African-American descendants of slavery? The former often benefit from affirmative action aimed at the latter.
