Spoken like someone who's never done housekeeping. 4 hours a day is a pretty normal amount if you need to wash clothes, sweep, mop, do a family's worth of laundry, prepare food, clean dishes, etc.
Yeah I am also wondering where this 4hr per day statistic is coming from. Dinner for two usually takes no longer than 1 hr a day, dishes usually put in the dishwasher every other day, and we reserve Sundays for cleaning, laundry and taking out recyclables. I cannot fathom anyone taking 4 hrs every single day to do housework, unless you have some kind of aversion to a dirty clothes bin or dishes piling up in the sink or Mr. Clean holding a gun to your head.
