I define "social stability" as a state in which people within a specific society don't kill each other in large numbers over questions of resource distribution.

I define "social stability" as a state in which people within a specific society don't kill each other in large numbers over questions of resource distribution.

Except if you own a spaceship or an island far away so you can leave if things get too hot - then maybe you find the goal of maintaining social stability unnecessary.
