Where did you get the idea that China is rich?
As a country, China is still poor. The only reason it appears rich is that they were starting from such a rock-bottom baseline that any improvement at all was bound to be spectacular. Sure, there are a few (OK, a lot) of people who own Mercedeseses, or even just Honda Civics. But that doesn't prove anything. Money is easily printed. And the hicks out in the boondocks are still living like peasants, same as they did for all 5000 years of China's glorious history.
As HH says (with slightly less cynicism), it's all smoke-and-mirrors; without any sound underpinnings or actual social progress, it can't continue. Even in our (supposedly) advanced economies, there is a natural cycle of ups and downs (the business cycle being about a decade, and the recession cycle about a century). In China's case, the only reason the upswing has continued for longer than usual is that China is BIG. They have a lot of resources to dig up, a lot of people to exploit, and a lot of leeway for making promises they may or may not be able to keep. They're on the start of a roller-coaster ride, and there's going to be a lot of screaming when they go over the top.
