Folks, China has problems we should be very glad not to have. Have listed all of them in previous posts here.
China's getting old before it is getting rich. The "one-child policy" is biting China with fangs or steel. The country is by no means evenly developed. Environmental problems due to rapid industrialization. Huge shortage of marriageable women in the 20-40 year age group. Lots of men who will never be able to find a wife. Other countries starting to supplant China as the low-cost producer.
Here's the biggest problem, as I see it. As people's economic situations improve, the more they want their political situation to improve. South Korea and Taiwan made the difficult, and not entirely bloodless, transition from authoritarian states to democracies. The Xi regime is utterly terrified of that happening. They are terrified of the growing Muslim problem in their west. They are scared shitless over what's been happening in Hong Kong. This is a regime that expends enormous amounts of resources (people, equipment, money) on suppressing dissent and dissenters. And I'd go so far as to say the Xi regime is no monolith. Someone inside the regime, maybe even Xi himself, knows of all these problems and more.
What to do? I don't believe the Xi regime really knows for sure. For now, they can get by doing what they are doing to their Muslims. Far as various social media goes, for every measure there's a countermeasure, and people are endlessly inventive. Looking at Hong Kong, they have no good choices as they see them, only bad and worse.
President Trump is doing the right thing re trade with China. Finally have a President who will stand up to those people. The next recession is key, I believe. We will sneeze and get a cold. China may start off with pneumonia. Should massive unemployment occur, there is likely to be widespread rioting. China doesn't have unemployment insurance like we do in the USA.
On the military side, China's got some new ships, new planes, lots of troops and tanks. China's last real combat experience was forty years ago. And I don't believe they have any combined-arms combat experience at all. With a deficient power-projection capability, unless they can drive or march across the border, the PLA's gonna have to swim.
Bottom line here...believe China is more a house of cards than many think. Anything can happen there, and when it does it can happen very quickly. You could be shocked, but don't be surprised at anything that happens re China.
Also a lot of their GDP is tied up in real estate scams
Yup, got a real estate bubble, a credit bubble, and a debt bubble. Just a matter of when, not if, any or all these bubbles burst.
