Particularly American? What does that mean? That parents in other countries are better than us? That they have more time, more know how, more wisdom? Sorry but that's stupid and insulting, which I suspect was your intent.
Not necessarily better, just less controlling. E.g. in Germany there exists an imperative to give children freedom despite dangers. Parents don't expect from themselves to be able to shield their chidren from all possible dangers either. Not sure if it's better, but it's a different parenting culture for sure.
It mostly extends to interactions in the physical world though - restricting children's use of digital devices is socially acceptable and expected
I have absolutely no faith in German intuitions regarding what is appropriate or inappropriate about the care of children. Ask me again in a century and I will reevaluate my opinion.
America is a huge place. You can't sample some professional city full of helicopter parents.
More nights than not, I have random neighborhood kids playing in my yard and eating dinner with us. Their parents don't seem to care, and neither do I. But I don't live in SF or NY, either. I don't mean to insinuate those cities are worse, I don't know, but cannot figure out where else that trope would come from.
