People learn and change: increasing numbers of women in education now will mean more relationships where expectations have changed in the future. This is likely to mean that, actually, some men with lower incomes than their partners stay at home to look after the kids. It is a natural consequence of an unequal society with greater parity of educational access. That's all.
It might suck for people who can't get over it, but on the whole, it'll improve society no end to see more fathers being full time carers for their children.
In all likelihood, we'll see a change of attitudes so that women will look for different things: domesticity seems the obvious choice. And frankly, it'll be nice to live in a world where doing the dishes is a personal characteristic that someone might value equally with income.

Not too related to the above, but the measurements of what women value is very likely to be WEIRD - Western, Educated, Industrialised, and the other two I forget. Economists have a hammer, so everything looks like a nail ($).
