your way of thinking is still wrong

Not sure that's how opinions work, but sure.

People always think something can't happen until it does, and the historical record of nations indicates that revolutions, civil wars, genocides and other major events actually happen much more often than people want to believe.

Yes, historically this is true. But that argument only works when there is precedent, and there is nothing in history that even remotely resembles precendent of a nation 20% the population of the planet, run and controlled and grown at this alarming rate with this much technology... it's not even just China. The idea that the US can be toppled by protests is laughable. The right to bear arms is essentially the right to shoot oneself in the face if the military come rolling in.

Sure, it's feasible according to the laws of physics that a big enough protest could topple a government of this magnitude, but there is no precedent and thus no evidence that it ever will. The very idea of expecting it any time soon is just kinda wishful thinking, I'd say. We could see a slow, or eeven a rapid decline over the next few centuries which cause massive internal conflicts between sects of the politburo of the CCP, this could be a more likely cause of collapse. But a protest in a tiny city that contributes very little to the social fabric or economy... nah.

I do not think you understand its economy well enough

I think I am quite well acquainted (I've written about it somewhere deep in Steem before). I just know what is realistic, and at no point with the US people approve of $600billion trade being cut off entirely - including precious metals in which almost all of it resides in China, and basically lead a short spiral into war. Nobody would want this, not the US, China, nobody.

I know their economy is struggling but as I've written in my most recent post, there are no limits to what they can and will do to maintain power, as historically this is exactly what they do, from cappinig and shutting down financiial markets to control the flow of trade according to their whims, to manipulating the sentiment of bitcoins, banning and encouraging platforms, controlling how many homes families can have an how long they can own it, manipulating the housing market entirely; even banning people from coming into cities if they're from certain other places, and forcefully shifting farmers into industrialized factory lifestyles according to an intricate plan I forgot the details of. In the same vein came the Great Leap Forward, and for all its heinous and horrifying truths, China's economy boomed.

The final point once again referring to the US revolution, that was a time of muskets and small boats. It's is only similar to the current Chinese scenario in vocabulary only; revolution. Revolting against a state that controls nukes, aircraft carriers and intercontinental missiles, is kinda daft.

Unless you're referring to the US going to war again rather than the small city of Hong Kong, in which case, again, nobody wants that and nobody will do that. It's just not in the interest of anyone at all
