As far as ancedotal evidence of a couple of minorities in college goes... That argument is pretty damned lame. I've seen PLENTY of rich kids go to school, not give two shits about their grades and basically live off of mommy and daddy for as long as they can. I knew a guy like that who pulled a whopping 0.0 GPA!
You can't judge an entire race (millions of people) by the stupid behavior of 1, 2 or 200 or whatever. THAT is what prejudism is all about! How do you expect people to get out of neighborhoods like many come from without a little help? Oh true, it CAN be done... but the path is much harder than it was for me who had a suburban upbringing, the best schools and all the opportunities life can offer.
AA has its place, that's for certain... Again I'll say I'm not so sure it has much of a place beyond educational institutions -- if a company doesn't hire minorities they have to answer to Jesse Jackson!!! (kidding, I had to go there though
). But seriously, the law is a bit flawed. You can't FORCE an employer to hire females and people of color to meet certain quotas... The change has to be voluntary so the culture needs to be changed.
