President Obama has called e inequality the “defining challenge of our time,” but is it strictly about paychecks? Ari Fleischer thinks there is definitely more to it; he believes it’s about the breakdown of the family and American rejection of marriage.

“Marriage inequality” should be at the center of any discussion of why some Americans prosper and others don’t. According to Census Bureau information analyzed by the Beverly LaHaye Institute, among families headed by two married parents in 2012, just 7.5% lived in poverty. By contrast, when families are headed by a single mother the poverty level jumps to 33.9%.

And the number of children raised in female-headed families is growing throughout America. A 2012 study by the Heritage Foundation found that 28.6% of children born to a white mother were out of wedlock. For Hispanics, the figure was 52.5% and for African-Americans 72.3%. In 1964, when the war on poverty began, almost everyone was born in a family with two married parents: only 7% were not.

Fleischer proclaims that the government can’t move enough money around fast enough to enough people to fix the kind of poverty created by single-mother-absent-father families. The War on Poverty de-valued marriage and men’s contribution to the family (and that contribution is not simply financial.)

Given how deep the problem of poverty is, taking even more money from one citizen and handing it to another will only diminish one while doing very little to help the other. A better and passionate policy to fight e inequality would be helping the poor realize that the most important decision they can make is to stay in school, get married and have children—in that order.
