The ancient Greeks had ideas about the κύκλος (cycles) of government: Plato's cycle went [aristocracy > timocracy oligarchy > democracy > tyranny]; Polybius' cycle was [ochlocracy -> monarchy -> tyranny -> aristocracy -> oligarchy -> democracy -> ochlocracy] — https://en.wikipedia.org/wiki/Social_cycle_theory
Yea neo-feudalism seems to be all the rage these days.
Democracy is not a given, people with power want more power and less checks - historically that’s what things converged to typically.
