Except the guys won’t play along, will they? Consider the strategies. An obvious one is to scale down, never marry, never have children, and live a circumscribed life with a not-too-challenging job, and enjoy however much sex you want via online dating services. Meanwhile, the women can work for their entire lives as hard as they worked in school, just keep going and going, shoehorn in a couple children, work harder and harder to pay for everything they need, including childcare. Work work work.
Grim!
