So, why are "they" the majority of the workforce, a clear majority of college graduates, and trending up in both cases?
At some point it's time to stop arguing about theory and look about you. It's over. The male-WASP free ride is over. Maybe we've hit balance, maybe we haven't, but if we don't want to shoot right past the balance we better start looking around a bit before blindly spouting arguments from the 1960s. At some point you get to active discrimination against male-WASPs. Note how I carefully failed to phrase that as a question. And if it's not time to at least discuss the matter in light of the facts of my first paragraph, when will it be? Give me a concrete criterion for when we know we're finished.
Had I asked that question 20 years ago, one imagines the answer would be "When parity is reached", but since we've shot past that and it's still not enough, apparently that's not the real criterion.
This is a broad problem with politics right now; nobody knows when to say enough! Enough money has been spent on education, enough pension benefits have been given, enough has been spent on the military, enough affirmative action has been done. There has to be enough sometime.
def enough_done_for(policy, effort):
return False
is not a policy, it's a recipe for suicide.
