You don't seem to think any large-scale economic breakdown is possible; trees just grow to the sky forever, eh??? Never need to pay off debts; just inflate them away, eh?
That's nice.
If they earnestly went capitalist and ditched the communism this wouldn't even be a hiccup. How many centuries has the lure of the teeming "mass" market of China been a siren call for Yankee merchants?
The only reason they can't kick their "US" market dependency...is the communists don't want to.
First, the PRC knows...and structures things...so that they are rising at our expense. Enfeebling our resident industrial base, and relocating it to their control. And accruing a large enough financial stake in our debts to undermine the dollar at a time of their choosing. Meanwhile, they lock up oil supplies via direct barter with rogue countries (Venezuela, Iran, Kyrgastan, Russia, etc. )outside the U.S. dollar system.
Second, they keep the vast majority of their populace out of the "new economy" for a very deliberate reason. They wish the main majority to stay totally engrained in their communist ideology. While encouraging the East coasters "to become rich is glorious" in fact, very few can, because wages and the currency are so rigorously kept world-beating low. This is a form of three-card monty. The only ones getting rich are the Communists who run the game. It is a choke collar that allows them to maintain total control. This prevents a true middle class from arising...which might not be so controllable.
