"No, because if it really turns out that what set of genitals you have play a major role in such a huge financial decision as what career you choose, even in the absence of outside coercion, then that instantly invalidates any economic theory that assumes people generally make rational (from purely economic perspective) choices - which would be all of them."
Not at all. Try to follow along.
The genitals you have, along with many other factors, shape you and what you desire.
'Rational choices' only acquires meaning here after desires are established. People chase their desires and in doing so tend to be more rational about it than they realize.
But if you really believe what you are posting then you should give equal time to recruiting more male nurses, and child development specialists, and also we need more female sanitation workers and firemen btw. Lots more.
