There is an upper bound to the loop. People die. People lose interest (thereby changing the population). People get annoyed and thereby more willing to do stuff to change. Not mathematically provable, but works in most situations because humans are adaptable. *edit: I feel a little disappointed that people don't seem get the humor in my post. Maybe dying because people voted chocolate ice cream but you wanted vanilla is a reasonable scenario for some.
