There needs to be something other than economic pressure to guide peoples' behavior or the demographic transition will depopulate the Earth.
In my unscientific observation families who have mom at home and dad working do very well, capitalistically speaking.
There are great hidden costs to not having mom at home. Like divorce, affairs, childcare, house cleaning, maintenance of everything, support for husband to go get it, driving, cooking, all that.
No. Greed wants women to work. My buddy one of seven children was raised by a stay at home mom with a working dad because they put raising a family over possessions. They live in a small home have one car and seem to be well raised and happy as clams.
