Gender as an organizing principle for how we value labor appears to have depressingly early, yet unsurprising, roots. Boys, on average, spend two fewer hours doing household chores per week than girls do (they play two hours more). And if they live in households where children are compensated for doing chores, boys make and save more money. Year after year, studies repeatedly confirm these patterns. The problems women face with unequal pay and housework duties actually start in childhood.
