In other word, hacking your fellow mens livelihood might shorten your longterm survival.
My pet theory is, that having suffered for nearly 10.000 years under castes of priests and noble men unwilling to lift a finger, humanity has developed a near instinctive hatred for "parasitic" entitys, who ledge themselves to society extracting value without returning anything to society.
The moment, external circumstances in such a system create a down turn, the whole thing explodes, viciously attacking the non-contributors, trying to exterminate them and redistribute there ill gathered gains back to society.
Take a look at france during the revolution for example. Sometimes the parasites, manage to redirect the hatred towards internal or external outgroups, like the jews in germany during ww2, but in the end, the mobrule undoes most of the parasitic growth anyway by sheer brute force and endurance of turmoil.
