Ghost cities, regional debt, Evergrande... pick one then show me what the real-world effect has been on their economy.
You do know that Chinese economic growth is
cratering, don't you? They had a long stretch where it was like 8%+ per year. But those days are gone, and they're never going to return.
And in what possible world could you ever think that China's demographic collapse
won't hamstring them? Seriously, how exactly do you think that could ever work? You do know that it takes a minimum of 20 years to make a 20 year old worker, right? The number of workers China will have over the next 20 years is already set in stone, it's already declining, and it cannot be increased by any possible government program. Nor have any of their efforts to do something about their demographic collapse had any effect on reversing the trend in the future either. China is literally dying.
When China has enough missiles to threaten USA they will announce they're taking over Taiwan and will target American cities if they interfere. America is not going to risk hundreds of millions of deaths for an island of Han Chinese.
Will China risk hundreds of millions of deaths for an island that's going to be rubble either way? If we do intervene to stop an invasion, would they really launch, knowing that we would strike back? Would that actually be worth it to them?
And here's an uncomfortable reality for China. Suppose that we promised not to interfere. Could China successfully invade Taiwan today? No, they could not. Amphibious invasions are really, really hard to do, and Taiwan has been preparing for decades. Yes, they're building up their armed forces, but it's not going to be enough, not any time soon. The problem is intrinsically hard.
China saw what happened with the Russian invasion of Ukraine. On paper, Russia should have steamrolled Ukraine. But they didn't. China has many of the same problems with corruption that Russia has, and no effective means to solve those problems either. And although China's military is larger and better armed than Russia's, Taiwan is likewise far better armed and trained than Ukraine. And again, amphibious assaults are intrinsically harder. If you think it's a **** show for Russian troops when the lead tank in a column gets taken out by a Javelin, just wait till you see a troop transport taken out by a mine. The Ukraine war was the death knell for an invasion of Taiwan.
You might argue that China's military buildup will mean that eventually they'll be strong enough. But that's not true either. Again, demographics is destiny, and their demographics are
worse than you think. They cannot continue the current rate of military expansion for the next 20 years. They will not have the spare economic capacity to do it, or the spare manpower to actually field as an invasionary force.
