> Government-funded cooperative breeding We already have that in the USA, it's called single motherhood and >50% of all new children being born are to this group. If any mating stategy is going to be institutionalized and government funded, it's going to be the female dual mating strategy (alpha fucks, beta bucks) (where females get genetic material from 1 group of guys or sperm donors and resources from another group of guys), not enforced monagomay or breeding coops as OP calls it. And we already have this.
