My friends who live in modern suburbs don't know their neighbors. People complain their kids don't leave the house... Where would the kids even go?
We need to end the tyranny of the non grid suburb..suburbs should be on grids. Most things should be within walking distance so children can be more independent.
Then it's like really easy to know your neighbor. I mean how could you not? You see them everytime you walk your kids to the park, everytime you're at the community pool, everytime you shop.
I grew up in a 50s suburb and even that was a world's away from what my kids get
Sometimes we've already solved our problems if only we're willing to look to the past.
