Had I known this before, I might have told Betty we had to wait until she learned to do more chores:
Within marriages, the study finds that women do about twice as much housework as men, even after adjusting for employment status and other factors. While men living with their partners do more housework than married men, women still shoulder the burden of household chores. (bolded for emphasis by yours truly)
What’s interesting, however, is that in cohabitating couples, the chores are split more evenly.
Every study I’ve read backs this up, and that women do more chores than their husbands seems to be true despite childcare breakdowns and employment status. One woman I know worked fulltime and made most of the family’s money and still came home to do most of the chores.
