There's two kinds of people benefitting on the short-term from hookup culture: vast majority of women and a select percentage of high-value men. The high-valueness is based on physical characteristics only, most importantly face and height (race too, pajeets and other nonwhites are at a massive disadvantage, but let's pretend we're in a fully white society).
Here lies the fundamental difference between the sexes: the main imperative of a woman is to have the best quality offspring she can have. She is the one giving birth, she is the sexual gatekeeper, she gets to pick her mate, not vice-versa. Thing about women is that they would rather die childless than get impregnated by a man that doesn't pass her genetic fitness test. This is why women are hypergamous by nature, the men they pick will in almost all cases be higher value than them.
Men on the other hand have one biological goal, spread their seed as far and wide as possible, aka impregnate as many women as possible. The genetic fitness means jack shit in this case, you'll find men will literally have sex with down-syndrome landwhales because the genetic fitness of the woman doesn't matter. Men don't have to go through the painful process of childbirth, so the most effective strategy is to spread your genetic code out to as many women as you possibly can.
This is the base human nature because we're extremely sexually dymorphic species. Women by default are born on the dead center of the bell curve (most of them are 100 IQ midwits) while men are born on the extreme ends (many retards, many gifted men).
(It's called the Variability Hypothesis) Essentially this is our species way of evolving, have women as the base and males are like throwing shit on the wall hoping some of it sticks (and it works). This is why in prehistoric times, 17 females reproduced for every one male.
(Source) Yes, for a female it is more desirable to be in the harem of one genetically gifted chad than to be in a monogamous sexual relationship with a subpar or even average male. It's why feminist championing "female sexual liberation" want to return to this instead of the tamed human nature we had with christian monogamy (that allowed us to build stable technologically advanced societies). A modern woman, even though she doesn't want to bear the responsibility of giving birth to children, still has the biological drive to have sex with high-value men (aka chads) and only high-value men.
Does this work in the long term? Fuck no. Which is why since society existed we had to be tamed either religiously or culturally to be monogamous. Why do you think whores are shamed across every culture on earth? The people who champion hookup culture, which are mainly women, are simply following their instincts. Because they want to get fucked by chad, simple as. Do you think a society can function in a stable way when the majority of it's male members aren't happy workers with families sustaining it but literal incels? The only men who support whores' freedom are either the top percent of men who get to fuck a different woman every night because there's no stigma against it anymore, and literal buck broken reddit simps who think supporting le wholesome chungus sex workers will get them laid (aka incels in denial).
I don't want to blackpill people. You can still have relationships with women, not all of them are retarded whores and also if you're white you're at a huge advantage. Engaging in hookup culture with non-whites at least for me is piss easy since I'm 6'3" white, but then again why would I want to? Engaging in hookup culture means you're following your animalistic instincts, you're operating on a lower cognitive level to satisfy your primal urges, which is what a nigger would do. In an abstract sense you're destroying society, which sounds dramatic but there's a degree of truth in it.
