I do understand about wanting to have some control over your living space and I'm glad about the conversation because it did remind me that I live in a rent-controlled apt.; naturally, this skews my view of things.
I don't know of sociological studies about suburban malaise, but I do know that that's where people tend to go postal. I believe that every single school shooting has taken place in a suburban school. As for the good neighborhood stuff you cite, I would guess it's more common in downscale than in upscale suburbs.
