Housing has never made my list. There are a lot of things I believe are more responsible for the destruction of our sense of community and the ties it brings to our neighborhoods.
I realize I’m biased by my upbringing in a single family home neighborhood so perhaps you have a different definition than I do. I think technology is the primary culprit. By expanding our view to be more global it diminishes the role of the local. Not sure if that’s an overall positive or negative.
