Though women still do more of the housework and child care, the so-called second shift scenario--in which working women are stuck doing all the work at home too--is less widespread than a decade or so ago.
The fact that men can do the grunt work at home doesn't mean that they will "naturally" do it though--usually the wife has to exert some leverage. Sometimes that leverage is her earnings; other times it's her ability to negotiate.
Unfortunately, the fear that abounds now is that the punishing economic climate may eviscerate a positive trend of more decision making by women.
