I think a lot of people who were born in the west don't understand that, when you're very poor, economic circumstances matter more than political freedom. After all, having money (or not) affects what you can or cannot do far more than whoever's in charge. Chinese people today have lived through an economic miracle. If I lived there I doubt I'd criticize their system, especially considering people still can remember…
Yeah I pretty much agree with you. It's very difficult to rule a large country as China and Chinese people generally respect that. Also like you said, the failure of those color revolutions just showed other people how important stable is.
When the young ruling elite encounters a crisis, a real problem, often they see that doing it in a transparent and equitable way would only serve as gunpowder for their detractors. Hence the very fast descent into totalitarianism.
And it's no wonder the real crisis of every regime is not some natural disaster, or economic collapse... no, in large nation states the game is entirely about the meta level, the power, and how to keep it, how to distribute it. Naturally this leads to the aforementioned populism/nationalism/etc.
