I don't know, hawkeye. I think if there will be anything to ever explain this it will be some sort of cultural explanation though so in that regard I think you're right.
At the risk of being lambasted by the feminists among us, I do think women have a lot more latitude in "proving" themselves. Men are still expected to "prove" themselves through employment, pretty much, so I get where you're coming from.

Everywhere you turn there someone talking head wringing their hands over science -- America is going to hell because we don't have any scientists, woe is us, our future is grim. And here's this kid who excelled at science. "The best of the best" was how one professor described him and he can't get a job.
Who does get a job? A bunch of beautiful, high school drop out, actors?
