“And really, if a woman has that much more earning power, who is going to raise several children, clean the house, and bake the challah?”
I don’t think this is such an issue. The children should be priority yes, but again we have washing machines, dishwashers, freezers and more access to household help than our ancestors had. So that frees up allot of time. Also children go to school for most of the day. Clean the house – if you work you can afford help for the time you would have spent cleaning. Challa can still be made or store bought.
