In case you didn't see this excerpt from the upcoming book Marriage Markets: How Inequality Is Remaking the American Family, authors Naomi Cahn and June Carbone find that working class women (in contrast to upper middle class women) do better economically as single moms. I didn't find the authors' conclusion in the least bit surprising: I see evidence of it all around me, every day.
In today's economy, many working class guys can't get or maintain jobs that allow them to contribute much in the way of financial support. Marrying such a man makes the woman responsible not only for providing for the child, but also her partner, and gives the man parental rights (i.e., shared custody) or control over her life that he wouldn't easily enjoy if she did not marry him.
Under these circumstances, choosing not to marry the father of her child is kind of a "no-brainer," especially if a woman has parents or other family members willing to help out with child care.
Is it possible this phenomenon is fueling the backlash that the "manosphereans" represent? Their fear of obsolescence is, after all, not unfounded. As the middle class continues to erode, and the former working class slip into chronic, inescapable poverty, the trend of mothers unwed by choice is unlikely to reverse itself, however much they are berated by the religious right wing. And the impotent efforts of the New Misogynists to shame these women are less menacing than pathetic, for they know and we know that those women they call "sluts" or "feminists" not only don't want them, they are better off without them.
