They didn't: the elite pushed sexual lib both so they could have more pussy and so the population would decrease with a society of women on birth control, all while doubling the workforce having men and women compete for jobs where before man worked 40 hours and could support a wife and a family with a home.
They carefully created a world where they are more powerful than ever, and you are more of a slave than ever. They know it's no longer a world where a few men with guns can change the situation, because it's no longer small arms and villages, but giant states and militaries, international internet social media jet-set vagina sampling for them, jerking off to pornhub for you.
There are blacked pornstars who have fucked countless 10s, while there are countless men who will now die virgins. Countless more men who will spend their life breaking their back and begging to sniff some average-looking sluts used pussy and dealing with her shit and social media yapping. Women's only value is their beauty in a world where they've been made dumb walking retweeters of the shit they read on Facebook that nobody gives a fuck about. They can't cook, they aren't mothers nor do they want to be, and their capacity to be a supportive wife is about the equivalent of Herve Villichaize to be an NBA star.
