> A woman is working for the money and whatever satisfaction she derives from the job itself. A man is working for his ability to attract a girlfriend, his status in society, his entire sense of "value". It's hardly surprising that men are motivated to choose riskier and higher earning careers.

I don't mean to go all PC police on you, especially since I agree with the first part of your comment, but this is most certainly not the case with most millennials (and even many women of the generation before). Most of the young women I meet today very much subscribe to the same notion of getting their sense of worth through their jobs, independence etc. So I would argue they are playing the same "game" in the employment market. However, our (US) society continues to propagate certain gender-stereotypes about careers which seep into all other aspects of our culture as well. e.g. its much more acceptable/common to be a female engineer in China and India. Now once these stereotypes are removed, you would see a lot more cross-participation which would be REALLY good for the US economy.
