Earlier in this thread I asked this question.
Well, historically speaking in times of war, civil war, and overall societal collapse of entire civilizations women become the prime targets for sexual rape. Historically it essentially becomes a giant huge rape-festival everywhere. In fact, during those periods of time it is a horrible time to be a woman as you essentially become numero uno on a target list by angry disenfranchised men in mass. Now that we have eighty percent of men removed from reproduction altogether thanks to hypergamy if a society collapse does occur women are going to have a lot of angry violent disenfranchised men to deal with and all of them are going to have a walking hard on. Good luck ladies should such an event occur. Under such a theoretical hypothetical scenario you would need lots of it.
If such an event occurs there won’t be enough male white knights to protect you all as essentially they would be outnumbered 3-1 and more than likely will be targets themselves also by the angry disenfranchised male mass that view them as their oppressors. [Imagine men hanging from nooses on lampposts everywhere with stab and gun shot wounds.]
The problem of depriving eighty percent of the male population of sexual intercourse, reproduction, and the ability to have families of their own is you take away all incentives of them investing or being involved in societies. Once you do that you essentially alienate huge numbers of men. That alienation turns into anger, that anger turns into rebellion, that rebellion turns into revolution, and that revolution turns it red violent war. Seeing a pattern yet?
If large numbers of men are not invested, connected, or hold any interests in collective society they will not defend it nor care about its overall inhabitants where they’ll be more prone to outright attacking it. What are the consequences of institutional female hypergamy? Violent revolution, discord, and societal anarchy. Congratulations ladies, you’ve got the world you’ve always wanted. 
Gangbang in a street alley anyone? Bukkake?
This is what the end of feminism and a government welfare female protected environment looks like below in photos…
Just looking at some of these photos of gentlemen hold guns, knives, pipes, and machetes I’m wondering how many of them would be thinking that women wouldn’t be laughing at them within that moment with such judgemental hypergamy. No, if I was a woman looking at these mobs of men approaching me I wouldn’t be laughing at all with my life in danger. If I was a woman I might reflect on how I was such a materialistic or selfish cunt towards men less fortunate than myself in the past where I would wish my own sex didn’t create such an environment that I found myself in at the time. Of course by then it would be too late with larger reactionary environmental consequences and such in motion.
