Right now there is a loneliness epidemic throughout the world. More and more people aren’t entering relationships. Gen Z men are having significant trouble dating while there are some economic factors in the mix. From my own view and experiences combined with what I’ve read most Gen Z men are lack the social and communication skills to even enter a relationship. This has and in the future will lead to extreme issues. There’s already been a marked rise in hostility towards women by young men (think Andrew Tate and his ilk) that’s likely born out of this frustration. I would definitely say there’s been a rise in gender hostility ever since the pandemic.
Back in the 50s there was arranged marriages. All a person had to do was just show but now that’s gone because it was an unequal system and I think society missed its chance to establish something much healthier and better in its wake. Now we have people that are unable to connect with each other. We just toss people blindly into the mess that is human interaction and relationships and no one knows what to do anymore. We could be have the most fulfilling relationships humans have ever had. Think of the amount of people who would of never have entered abusive relationships had there been someone around them that showed them what love exactly is.
The way we teach is so heavily focused on teaching people how to be worker drones that we forget the human part of the person. This is why a lot of people who do extreme well in school and college fare so poorly in relationships and have higher rates of depression. We are the most educated and advanced in human history, we know psychology, we can teach this shit rather than tossing people blindly into the meat grinder.
I don’t think you understand what the term “nuclear family” means in a sociological manner. In humans it’s not just “two parents taking care of their offspring”, there is also a caveat that they are doing that WITHOUT the reliance of an extended social group. Then those offspring are expected to do the same once they reach adulthood. The only social support they are expected to have is their own unit.
Furthermore, comparing human behaviours to other species such as birds (who flock together in habitats for survival and for migration) and possums (who are a solitary, nocturnal species) doesn’t really mean anything.
The comparisons should be to species who share similar evolutionary patterns and social habits to humans ie. primates. And across every primate species, whether it be lemurs, gorillas, baboons, simians, etc. they are all connected to a LARGER SOCIAL GROUP irrespective of their family structure (pairs, group family, homogeneous male or female) well into adulthood.
