This is based on the assumption that everyone who benefits from AA. I find this stance interesting from someone who goes on and on about "human nature" all the time.
The vast majority of that next generation is still growing up with all the same crap that their parents dealt with. AA did not change any of that. AA can't.
I don't think everyone benefits from affirmative action. Some people are better at adapting to culture change than others. My whole point in bringing up human nature is that we are all, to a large degree, products of our environments. Some of us adapt more to the environments we experience as adults, some stay primarily the product of their childhood, but we all come from our environments.
Changing a culture is a slow, laborious task.
