I hear you. I have been married 46 years. I would hate to be a young guy today. My son is mid 30s and never married. His long term female relationships have been a disaster, one after the next. After several of these he is not even trying anymore. He plays golf and finds it much more enjoyable.
My children are still teens, so I don’t know what lies ahead for them, but they are aware of the dynamics today (it is practically shoved down their throats) so they’ll probably end up in the same boat.
Some people seem to be doing OK marrying traditional foreign women; they may go that route. Your son has to be mindful that as they age, women who want families will say just about anything to get them.
Sadly, I think this is becoming all too common. But I don’t blame them after spending time around today’s young women. Maybe around 10% of them are even worth having. The rest have joined the eternally angry pussy hat marchers ... no man should ever have to endure such torture throughout their lifetime as to be married, or attempt to be married to such a critical individual.
