That's true. I think some schools now do make a differentiation between the types of Asians, which happens to be more about socioeconomic status (again).
I'm not against AA. I don't have a problem with it. If you can get into a school, and you can compete with your fellow students, then good for you. The people that shouldn't have made it in will wash out anyway.
(BTW, I feel like I know way more kids from 'richer' families flunk out of college than from poorer families, probably because the poorer kids actually had to work really hard to get to where they were, whereas many of the rich kids, once away from their nagging parents, didn't have self-discipline and drive. So.. it balances out IMO.)
Don't get me wrong, I'm not denying the evidence the Asians have to work harder to get into more prestigious schools. It's also the same in the corporate world. I think Asians should definitely be treated the same as whites in admissions but from the data being shown, it clearly is not. I don't think that means we should get rid of AA though, and you seem to agree with that. I think it's definitely a problem just like how blacks and hispanics are discriminated against in many aspects of society. I'm just not well versed in the topic enough to suggest a solution. However, complaining about it is something people should do especially if it's an undeniable fact.
