"being a man has no particular meaning anymore"
And unfortunately, men are also not needed much anymore. I read somewhere recently that people are descendants of many more women than men (meaning women have children more often than men - few men are fathers).
Women not needing the money of their spouses - will they really just be attracted to a wider variety of men? Another thing I read recently is that women are becoming more likely to care for physical attractiveness now. Good for them, but I can't really see the benefit for men gained from that.
Also what tires me is the assumption that women where held down by barriers we erected. I think in "former times" it simply wasn't possible to survive alone, and the traditional roles where one successful approach to managing life. Women were supposed to do the household chores because men were working at their jobs earning the money.
What really freed women therefore was not the destruction of barriers. It was the invention of dish washers, vacuum cleaners, washing machines and frozen food.
