Why not socialism?

Sobre el libro Why not socialism? de Gerald A. Cohen publicado por Princeton al 2009:

There are times, G. A. Cohen notes, when we all behave like socialists. On a camping trip, for example, campers wouldn´t dream of charging each other to use a soccer ball or for fish that they happened to catch. Campers do not give merely to get, but relate to each other in a spirit of equality and community. Would such socialist norms be desirable across society as a whole? Why not? Whole societies may differ from camping trips, but it is still attractive when people treat each other with the equal regard that such trips exhibit.
