Here’s a possibility -
Men have always pursued women. Womens’ job was to step on the brakes until they see a child-raising partnership.
Women think they don’t have that responsibility any more because of birth control, careers, etc., and they find that they kinda like sex just for the fun of it and it really is fun.
Result, accidents happen and neither party wants that child-raising partnership with the baby daddy.
So you have mommies (unless they abort) and the daddy gets the blame for disappearing. But the mommy is equally to blame. It’ the nature of men to roam and the nature of women to feel close to their children and not roam.
But time marches on. Nature taking its course. Then there’s the influence of low-life entertainers. Well, we know their acting is low-life. They are emulating their own peers and trying to make a buck.
There’s a pretty simple fix for all that: stop awarding child support and welfare to unwed mothers. Women would start closing their legs until they got a ring real fast, or they would at least be much more careful about birth control.
But instead, we’ll keep subsidizing having children out of wedlock, and like anything we subsidize, we will get more of it.
