Inequality would be even worse and upward mobility would be reduced, at least in the west.

You're right that you can't have a Pharaoh without a huge society built around one, but you don't get that society without a professional force policing the farming of the Nile, and you don't get successful farming of the Nile without a police force strong enough to oppose resistance / enforce retribution on "cheaters" with regard to water redistribution.
Regarding revolutions: sometimes the govt realizes it has a cancer and takes steps to cut it out or irradiate it. Sometimes the cancer wins and the entire body dies. Out of the ashes typically rises...autocracy. You only get something else when the power brokers actively strive to make such a thing, and even then you still frequently end up with autocracy.
History. Go read it.
The same principle applies to colonialism. The British in India, the French in Indochina, and countless other examples from history: the imperial power always needs support from the locals, usually the elite or in some way privileged classes whose welfare becomes tied to the rule of the imperial power.
This is true in China, but it's true everywhere else. It's true in the west. If people stop complying we would get way more power and overall reduce inequality between the few rich and powerful and politically connect and you everyday Joe.
For the same principle, Russia could never control Ukraine without support, the romans couldn't control their provinces without local approval.
