E. L. Doctorow novelist Communities appear temporally rather than spatially. They form as circumstances demand, and when the emergency is over people go back to their semi-estranged mood. A surgeon who only wants to make money and live well and has a lousy bedside manner still contributes. The Korean grocer on the corner who works hard trying to survive may feel a foreigner, but the store is a contribution to the neighborhood. I don't know if you can ask for more.
Community is a bit of a joke.
Only labor has succeeded. That's why business hates unions. They can create real community and democracy. Our inordinate concern with individuality has marked our group identity. I'm part of the problem.
