Terence Jeffrey: “Married couples with children under 18 years of age, according to the Census Bureau’s Current Population Survey (Table HINC-04), made an average household income of $107,054 in 2013 and a median household income of $85,087. … [M]arried couples with no children under 18 had an average household income of $91,870 in 2013 and a median household income of $70,995. … Unmarried couples with children under 18 had an average household income of $65,337 and a median of $50,031. … Unmarried couples with no children did only a little bit better, with average household incomes of $76,609 and median household incomes of $62,126. … Why do married couples with kids have higher household incomes? Perhaps it is because they are not primarily driven by greed but something quite the opposite: a willingness to make sacrifices so their children may live better lives. It is telling that married couples with children tend to end up with higher incomes than people who only need to maintain a household for themselves. And it is a telling irony that some politicians would like to redistribute wealth from the former type of household to the latter while making fewer people dependent on themselves and their families and more dependent on government.”
