That's the thing, at least in the case of college admissions anyways, is that this doesn't do what it claims it does.
It's been found that Affirmative Action doesn't hinder white students from gaining admissions. Instead, it mostly just hinders Asian students by replacing them with Black and Latino. Not by a little, but by a LOT. The root cause has to do with the percent of those applying doesn't match the percent of those members of the overall population. So they feel they need to correct it by dumping off a few perfectly qualified Asian students in favor of some potentially less qualified Black or Latino ones.
Somebody speak out if I'm wrong here, but in this age of "white privilege," how is it that Asians are any less disadvantaged than Blacks or Latinos? Historically, Asians have been every bit as downtrodden in western countries, and blacks aren't the only ones who can claim being victims of slavery in western countries either (few people seem to know that Irish slaves were also common in the Americas at one point; in fact during the mid 1600's, Ireland's population dropped by almost half due to slave exports.)
The only explanation I can come up with is that since Asians are culturally very disciplined, they tend to excel academically. Likewise, you see more of them apply, and thus see more of them do well. I think whites are only slightly less disciplined than Asians, so they come at a close second. I'm generalizing of course, but when you look at the kinds of values that black culture has, it does fit the narrative (Bill Cosby once lamented this, how he hears of other blacks who often describe being successful as "acting white," as if it was a bad thing.)
But what do I know, I'm just one of those white guys who deserves to have the word "privileged" written across my face in permanent marker and therefore I can't possibly see racism due to my color.
