But don't forget at the same time where China was during the end of the British power, nor Chinese revolutions, nor the state control over the Chinese populace.
Although the US vastly overweights what we think non-US-democracies would do (think Middle East and our meddling there) given the chance for US like freedom, I do not think we're seeing China in the natural so to speak. HK, for example, was not pleased with the "two systems one country" rule the CPP landed on.
Add in the fact that trade can no longer be assumed to be Chinese central, and China is slowly getting dragged into wars through Russia, and China still hasn't tried its mettle with Taiwan. A post invasion China will hit different. It's got internal issues of employment, real estate, have v. have nots ... it's got its hand full.
My guess is that China, like the US is seeing now on stretches, will be the master of its own demise. In the US a major contributing factor to Trump is the fact the US Congress has become an institutional zero especially since Gingrich. That power vacuum has been filled by the Executive branch under Trump. There's more to it of course, but this two-part crisis is an important matter to keep in mind.
China takes its state craft more seriously in some sense, but that seriousness may get it into trouble. And in fact, several articles in the Economist have argued that if China wants to keep 5%+ YOY GDP growth, the CCP will have to take a back seat which is the one thing it will not do. CCP political power is foremost; good economy is damn nice to have to when you can get it -- and the CCP will go after it hard -- but there are limits ...
This and Citizens United.
But besides, with the rightward, populist/religious nut tilt of the US and corporations being able to bribe the President to get what they want without repercussions (Disney, Paramount, Meta, X, etc), I don’t see how the US is much better. All of the branches of government are giving power to the President that should be theirs.
Equilibriums in geopolitics are inherently unstable, states naturally compete for their own self-interest. No state will be willingly co-equal with another unless some actor with greater power forces it into that position.
To your last point, given the state of the US, it would probably be better for the world if the EU were on top at the moment. But they will not be.
The US has given me all sorts of opportunities I wouldn’t have anywhere else in the world as a native born citizens. I plan to extract as much as I can from it and keep my eyes open to retiring somewhere else.
I continuously vote and advocate for policies like universal healthcare, pre-K education, etc. But what are you going to do when voters vote for politicians thst ars against their own interests - getting rid of FEMA when the states that need it the most are Republican, Medicaid, etc.
This isn’t a pie in the sky shrill “I’m leaving the US tomorrow”. But my wife and I already did the digital nomad thing domestically for a year starting in late 2022 and going forward starting next year, we are going to be spending more time out of the country in US time zones while I work remotely starting with Costa Rica.
It doesn't need to turn the US into some grubby mafia state. It could, but I think it is unlikely. But the road for both the US and the world IMO goes down before it goes up as many systems and alliances around the world that depend on US domination shift or crumble. My 2c.
