A lot of women quit their jobs to stay home for years with the kids, the husband leaves, and she has nothing. So it’s wise for women to have an account incase the marriage doesn’t work. It’s also wise for a man to have a separate account incase the women decides to wipe out the account, and leave. Even when women work, they still do the majority of the cooking, cleaning, and child rearing. Most households aren’t a true 50/50 split in terms of labor. If you paid a personal secretary, chef, housekeeper, and full time nanny, it would be more than her income.
I was supporting myself before I met my wife, so her income wouldn’t make that much of a difference anyway. She works full time, and covers her own clothes, shoes, hair, nails, lashes, car payment, gas, insurance, credit cards, student loans, and all our vacations. We went on 4 vacations last year, 2 so far this year. And she still surprises me with random clothes, cologne, picks up socks and wife beaters from Target, groceries, brings home takeout etc. It works for us.
