Forget SSM -- straight marriage is the real crisis

But while straight young Americans support marriage for gays, increasingly they opt against marriage for themselves. Nearly half of American children, 48%, are now born to unmarried women. Among women without college degrees, and of all races, unwed motherhood has become the norm.

This is the crisis of the American family. Whether same-sex marriage proceeds fast or slow, whether it extends to all 50 states or stops with the current nine plus the District of Columbia, the crisis will be the same.

Children born to single parents face much longer odds in life than children born to married parents. (A new study by ThirdWay.org suggests that the harms are especially intense for boys, less so for girls.) “Odds” are not rules, of course. There are always exceptions.

On average, however, children born to married mothers and fathers are more likely to finish college, more likely to avoid prison and more likely to form marriages themselves than children born to single parents. And precisely because the harms of single parenthood tend to be self-replicating, the breakdown of marriage threatens to harden into a caste divide, with some families launched into cycles of downward mobility because of the unstable relationships of parents or grandparents or great-grandparents.
