Even within your world view (gender asymmetry->unhappiness for men), I don't see how men have less power than women except in the sexual sphere (because of your asymmetry); in all other areas I don't think they're so little empowered. Also, notice that the 'world we came from' (with, as you put it, men and women having both real power and real problems) was in many ways quite similar to the world in Afghanistan and the 3rd-world slums that you don't want to take into account, at least with respect to what I think you mean by 'men and women having both real power and real problems'. Both actually don't look very good.
