Most of those women that don't have kids or aren't married are because either they don't want to or are trash women (unattractive, hoe, crazy).There are more women in every age demographic than ever before who have never been married never have kids..
Women adapt to what the market is.
Most these women can't even find a good man so yes they ain't going to do nothing and ride it out
You guys are talking about SELLING a non legal marriage to attractive woman that WANT to be married. If she didn't want to be married then that's just a long term relationship no need to even go the non legal marriage route.
Many women are in long term relationships with no marriage but they not changing last names and have wedding ceremonies just for the he'll of it.
