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.
