I think the more successful they are the more the single mothers are absorbed from the realities of biology and suffering from the "cut flowers" illusion we all have, where we think this civilization is sustainable without the roots of religion or in this case the social constructs we built through tradition. (the two-parent family)

You see this now in Japan with more and more boys being raised by single mothers. The kids who grew up that way seem alright for now, and they still had Japanese society to lean on alongside their parents. What you don't see yet is what happens when a large number of those boys have become influential in culture - especially pop culture. They will gradually push the Overton window away from good culture that built their country and closer to gynocentric values that weaken society.
