The assumption is that men are generally doing well under the current system, so nobody needs to encourage men to pursue careers dominated by women. I am sure there is a notion that nursing is a feminine career, but that is beside the point; the real issue is that nobody is trying to dispel that notion. The effort is focused on dispelling the notion that engineering and science are "manly" disciplines. It also does not help that here in the USA we are trained to be automatically suspicious of men who pursue two common and traditionally female lines of work: elementary school education and childcare. A male kindergarten teacher is always at risk of being branded a pedophile by some paranoid parent, and must watch his every step in his personal life (what if he is into S&M? what if he is gay?).
