Q4ALL: Is it true that female sexual hypergamy was constrained in the past, but now it has become unleashed, and now it threatens to lead to the breakdown of Western civilization?

There was this comment on a previous thread:

the end game of fully unleashed female sexual hypergamy is the breakdown of Western civilization, the nuclear family, and the demographic decline of the white race

In response to this comment I asked:

How will fully unleashed female sexual hypergamy lead to a breakdown, and by what means was female sexual hypergamy constrained prior to this dangerous unleashing?

This was the response:

Unrestrained female sexual hypergamy has created a system wherein most men hardly ever get sex while a minority of geneticallly superior men (Chads) get all the sex. Because we no longer have a traditional society with Christian morals, and traditional gender roles within the context of marriage women are now free to make their own money at a shitty non profit job and put off marriage until they are in their 30s, or just do away with marriage and kids altogether. The patriarchal and traditional structure of men working and women being home makers in the past was the stabilizing factor in society. Now more and more men are dropping out of society and becoming unproductive because there is no longer any incentive to be a good provider. Women don't need a provider anymore, they just need a man for his looks and sex appeal. We've essentially reverted to a Hobbesian "state of nature" with regards to sex. Women are largely choosing to have sex with men based on raw physical sex appeal and nothing else.

because of this breakdown of the traditional nuclear family structure and the increasing number of childless women or single mothers we are headed for a future of decline until the wheels fall off this society and some sort of collapse and reset takes place. I don't this system is sustainable barring some miraculous technological advancement that allows human beings to be free of doing any kind of work.

To inspire discussion, let me copy/paste another comment to challenge this view:

All hypergamy was constrained in the past, male and female. People were shamed for stepping out of line socially. Divorce and cheating were huge social risks, not so much today. The redpillers love to blame women, society, feminists, globalists or whatever they can in order to not have to admit to themselves that they are the failures of the sexual market place, so to speak. Society as we know it may change, doesn't exactly mean that its a decline or apocalyptic, it's just a new social order in which they see themselves as powerless so that is terrifying for them. The idea of the 1950s nuclear family dynamic as this utopian dream is just the typical romanticism of an earlier time, there were many problems back in the 50s, people were not magically happy and satisfied with their lives any more then they are today, for instance alcoholism was rampant. Most people, of any era, live lives of quiet desperation. Always filter what you take from the red pill through the lens of who they are and why they are red pill. People that are successful, happy and fulfilled in life do not spend their days analyzing life strategies and screaming angrily into the void on the internet, they are out living life. Don't take it too seriously. There are some interesting points but a lot of it is the rantings of bitter men.
