"They're segregating based on race and gender, not class or socioeconomic status"

Socioeconomic factors are the more ideal consideration on paper, but in practice it doesn't matter, since that status tends to be influenced very heavily by racial/ethnic factors. Hopefully this'll change someday and we'll all live in a Star Trek utopia. Today is by absolutely no means that day.

"Does it really matter what color your skin is, if you have a MBA from MIT? How does that improve the cultural bottleneck?"

Wait, so just happening to have a degree from a prestigious college suddenly makes someone immune to the effects of racism? What a wonderful thought.
