The sexual revolution has not liberated women. Its merely liberated men from any responsibility towards women. I find that women (and children) have been the biggest losers of this trend to noncommittal sex and promiscuity.
In the past, women would marry young, become mothers, and raise a family.
In today's society, women are encouraged to marry late (if at all). So they spend their 20's chasing after a small percentage of desirable males (who, thus having lots of options, have no incentive to marry any of them). Then they arrive at their 30's, ready to finally "settle down", and find a scarcity of good men willing to settle for their high-mileage selves.
