You also lump Asians and white people together in a way that's inaccurate. In fact, by some accounts, white people are the largest beneficiaries of current college admissions practices at top universities, thanks to legacy admissions practices / donations, a preference for athletes, and race-based admissions policies.
I recognize the last two of these may seem counterintuitive, so I'll explain. With regards to athletics, the sports represented at top schools lean heavily towards those played in affluent, predominately white areas — think squash, crew and tennis.
With regards to race-based admissions, yes Hispanics and black people benefit (to be fair, they almost never benefit from legacy), but the real "victims" are Asians, whose representation at Ivy League schools has remained flat since around 1990, in spite of the fact that the Asian American population has almost tripled over the same time period.
