Consider the reasons for non-attractiveness. In the case of nursing, it's bad pay as well, presumably. In the case of IT, the general unfriendliness is one reason, though there might be others. Shouldn't we just remove the removable ones?
(I don't first-up reject the theory that there might be 'biological' reasons that apply to the majority of people, but we won't really find out until we try. And there will always be outliers.)
(Why, you ask? So that when I walk into a room, I could be the boss too, and not automatically be tagged with 'secretary'. It's about status and power in the end, maybe?)
