China Trouble Foretold

China's economic health is looming on the horizon as a concern. A housing bubble combined with an undervalued currency is my longterm concern for the Chinese economy. The question I have is where is the income going from China's economic grownth. Is the man on the street feeling more economic benefit or just a strong nationalistic sense. The Chinese have done a great job at maintaining stability in the face of a lot of real social challenges. My concern is that any rocking of the economic boat can unleash some real trouble. Particularly the second class citizen system that segregates rural from urban.
