What about young women? Aren't they supposedly the gatekeepers to procreation? The ones that have evolved to choose what's best for their kids (a two family home)? Did they stop choosing right?
The incentives changed drastically for women. You used to have to be married to a man to access his coffers. Try collecting alimony or child support from a guy who can move 100 miles away and essentially be unfindable. Now all you need is just a dna test and the state will hunt him to the ends of the earth. The state, through welfare, has also provided a higher bar than some lower class men can provide for women.
