Isn't necessarily fair....it could be more fair though (or, lead to a more net happy/harmonious world regardless of "fairness", which is a subjective term so fairly misleading anyways).

Besides: the masses are subject to the whims of the rich and powerful few on the regular, perhaps they should be subject to the whims of the masses at least occasionally.
