It’s the main criterion. If the system doesn’t last, then it’s shit regardless of what it is. The main purpose of the government (and any organization, for that matter) is to exist for as long as possible, everything else comes second. I wonder what other criteria do you have in mind?
We await patiently for your demonstration.
What’s the longest lifespan of a democratic state in human history? Now compare it to the average lifespan of monarchies, for example.
The ancient Roman Republic, lasting from the overthrow of the kings in 509 BC to the establishment of the Empire in 27 BC. This constitution was characterized by a Senate composed of wealthy aristocrats wielding significant influence; several popular assemblies of all free citizens, possessing the power to elect magistrates from the populace and pass laws; and a series of magistracies with varying types of civil and political authority.
There may be longer ones (e.g. Ancient Egyptian, Indian, Chinese, and Japanese dynasties), but the Habsburg’s rule is listed from 1282-1918. The Habsburg monarchy, also known as Habsburg Empire, or Habsburg Realm (/ˈhæpsbɜːrɡ/), was the collection of empires, kingdoms, duchies, counties and other polities that were ruled by the House of Habsburg.
Roman Republic wasn’t a democracy. It was ruled by aristocratic families. Lol.
The measure of whether a system of government is good or bad is not “how long it lasts”.
