Abstract: The widening gap between rich and poor is often painfully obvious from everyday news. But how did we get this far? Physicists have recently made interesting contributions to enlighten the situation. Methods of non-equilibrium statistical physics applied in the context of evolutionary game theory indicate that social diversity is indeed beneficial for the evolution of cooperation , and that highly heterogeneous social states may appear spontaneously via very simple coevolutionary rules from an initially completely non-preferential setup . In essence, the findings convey the potentially disturbing message that large differences in status may arise spontaneously, and although they might evoke discomfort within the majority that is disprivileged, they are vital for keeping the population in a cooperative state.
