The rise of out-of-wedlock childbearing is directly linked to the stagnation and decline in men's wages over the past four decades. Single parents are the canary in the coal mine, revealing the location of economic instability and decay. Look at the numbers and you can see the segments of the population in which men have the most difficulty finding a stable job that pays a living wage. The fact that "across Middle America, single motherhood has moved from an anomaly to a norm with head-turning speed," as the Times article notes, should set off alarm bells.
It's not about morals. It's about men.
