ironically, women's empowerment could eventually lead a society back to pre-historic times in a genetic sense. imagine a society where women no longer need husbands or fathers for either income or childcare (which is the current trend in the OECD). imagine further that there is no more stigma towards artificial insemination. then women will pick the fittest sperm from the bank (let's say an Olympic athlete with a Nobel Prize). thus we have reverted back to a time when the alpha males sire a far greater proportion of progeny. what kinds of long term effects are there on a society's gene pool? does this society then have less diversity, and thus decreased overall fitness as a whole?

what happens to the vast majority of prospectless men? mass immigration of females is one solution. but eventually the donor country will bar them from doing so. so imagine a country where 80% of single men will not get a chance to produce offspring. is that a recipe for civil unrest?

without any traditional patriarchy, it is in the female's best interest to get inseminated by multiple alphas. maybe there will be a social movement that that says for every alpha baby, a female must bear a baby with her beta partner?
