B. F. Skinner dreamed that people can be scientifically (behaviourally) trained to live together and described his vision in "Walden Two". It is interesting that the book spawned quite a few attempts to do that and some have survived longer than usual. I think one such community still functions someplace in Mexica, but do not know how close it remains to Skinner's ideas.

Monks live together in harsh conditions just fine. This is a specific community, of course. Yet this is also the answer: you need something bigger than yourself to submit your wishes to.
