Once upon a time, there was this decade known as the 1950′s. In this time, women were mostly viewed as housewives. Husbands went to work, and wives stayed at home, raised the children, and kept the house up — laundry, cleaning, cooking, running the necessary errands, etc.
The clear gender roles were that the man works at a paying job and provides financially for the family, and the woman stays at home and makes sure everything in the home and with the children is taken care of. This was the “societal norm” at the time. However this setup tended to devalue the capabilities of women, and empower men, which set up a power hierarchy in the family (based on income).
Fast-forward to the present, and we have a world where a one-income family is rare, both parents generally work, the children are commonly cared for by nannies or other forms of child care, and the home is kept whenever there is time to make it happen, or by hiring outside help.
