This article is full of naive propaganda bits (state-owned roads destroying state-owned schools), but it has one important observation.
China has been keeping its currency pegged to the dollar and lived off US consumption. Now US will not be consuming much for a long time, so China has nowhere to sell their goods to. Unemployment and riots are at hand, it seems.
Of course, that's wrong. China can and will continue growing, but this time the engine of growth will be their own consumer market. Which is huge. There are already more internet users in China than people in the US.
When renminbi will start appreciating vs. other currencies, the population will start feeling richer and will consumer more, import more and borrow more. Today they already have shortages of consumer goods on the mainland, such as cars, even though dozen of producers are struggling to keep up with demand.
China, in other words, is where Japan was in the 60s and early 70s (maker of transistor radios and cheap scooters, export-oriented mostly). And it will go on to become what Japan was in the 80s, only with 1 billion population.
