Agreed. I do remember reading somewhere that the average current full time working mother spends more time with her children than a housewife in the 50s. Children used to go outside and play and have more unstructured time. I feel like there is this whole odd child-centric culture in the US. It is bizarre how many young adults I meet nowadays who have not been left without adult supervision for more than 15 minutes their entire childhood.
Most of my friends are from childhood. For the ones who have children, about half of them have turned into uninteresting people who are incapable of carrying a conversation about anything other than their children. And some of them were extremely interesting beforehand. A few have snapped out of it when their kids have turned 3-5, but most seem stuck forever.
When I go to visit family and family friends outside the US, they all have a bunch of kids but none of them have this disease where they can only talk about the kids. But there's also much more family support nearby and societal norms allow the children to be more independent.
