You want to go back to the 50’s? Have all the working women quit their jobs, go home, get married if need be, and start having babies (and stop aborting them). That will bolster Social Security, reduce unemployment, and fix a lot of social ills.
Many families would be financially better off with one income. After you consider day care, transportation, wardrobe, more convenience foods and eating out, and the higher tax bracket, many women don’t actually bring in anything extra to the family finances.
