ok, Voland says, cooperation is a well established cultural practice; this doesn't mean that human nature changes(d) much.
I find it's very interesting that behaviour of the so-called 'the poor' and 'the rich' depends on the same (genetically programmed, reward system etc.) mechanism.
Voland says that some people are more greedy ('more sociopaths') than others and of course, that well established people make more harm with their behaviour . That#s somehow the same that already Platon / Thukydides, etc. said about different classes of human beings...
Voland strongly supports a proof of game-theoristical view in daily behaviour+Erich Feldmeier
