Well, local history in the US, judged by most current Americans, would probably say the current system is better than the previous one, and the current one spawned from a revolution. Maybe the second (third?) time it'll incrementally improve at least.

Almost every new system of governance has been better than what came before.

If revolutions inevitably make government worse, humanity collectively must be in the worst form of government in human history.

Which is why we are still living in nomadic tribes following chieftains.

No wait
