One interpretation is that we're in some kind of awkward middle stage where women are trying to fill multiple roles (perform well at paid job, look hot, take care of the house, raise kids, manage family's health, have a social life, etc.) I know I was raised with the message that it was important for me to be good at all of these things, and I would feel more a failure if I didn't do them all than I think my husband or most men would.

I can imagine that women's satisfaction would increase if role expectations were more egalitarian.
