"Community" v. "Gated Community".
Nice phrasing.
There is a site on the web with stories of British children and their experiences with bomb shelters in WWII. The government gave folks the rudiments of a small shelter, and all the neighbors would pitch in to help the family to install it. I posted the site here but got no response.
The kids talk about the sense of community while sitting with their families and/or neighbors in these things. The shared scarce food, always found space for each other, and everyone helped everyone.
Contrast that with American survivalists, who are prepared to shoot anyone who approaches their shelter, who are so worried about someone having something they don't, who are so paranoid one must assume they are themselves the real thieves.
