When I look at instances in my social circle, it seems like it doesn't really work. The relationships typically seem to suffer from a lack of mutual interests. The woman's beauty quickly dwindles as time passes. And the woman feels like she is missing out on a "real life" because all she does is be at the side of the man, instead of building her own career. The attraction of the man seems to dwindle quickly too. I know a few such couples, where the man told me that their sex life is dead, even though he wished it were different.
What that tells me is that to work on your attractiveness, working on your career is not the way to go.
