No , what I meant by "isolationism" was disregard for other people. My point was that it's not a matter of urban vs. rural. In my semi-slum childhood neighborhood in the 1940s no one ever locked a door either, and, as I said, everyone looked out for each other. No pigs to round up, but neighbors to help in other ways if necessary. Children were safe and could play unsupervised but someone was always around to watch and step in to discipline or rescue as necessary. The crowdedness in fact was a kind of security -- always someone there to help in a crisis. And help they did. The difference seems to be in a worldview that's changed.
