“Washed up whores with other guys babies do not wife up well.”
Just as abusive lazy bums who’ve abandoned their babies do not husband-up well.
The bad-boy bums are not going to marry them anyway.
The single moms want the good guys for husbands. The ones they scorned and spurned when they were partying with the bad boys. But increasing numbers of good guys want nothing to do with raising another man's spawn, especially since family courts would likely hit them for child support upon breakup (since the bum likely has no assets to garnish anyway), and are looking for young women without baggage.
The “abusive lazy bums” don’t dream of being married and rescued from their own situation, and cry on the internet about not being married.
Because marriage largely benefits only one side of the relationship, and it isn’t the mans’ side.
