4 possible futures

a) Egalitarianism and abundance: communism
b) Hierarchy and abundance: rentism
c) Egalitarianism and scarcity: socialism
d) Hierarchy and scarcity: exterminism
Note that the first thing the hierarchy does in b) is to create artificial scarcity via things like IP law, the wars on proper nouns and such like which then inexorably leads to d)
