The real reason why China built all these unused, unoccupied cities for millions is that is artificially increased their GDP. Many of these cities were built with ‘Stimulus Packages’ to produce work for a product no one needs. Another major part of China’s inflation problem is the price of food, which increased more than 11 percent in the past year. While some of this increase has to do with changes in international food prices, much of China’s problem is a function of increased agricultural wages. As has been pointed out elsewhere, the pull of higher wages in urban areas has left China with a depleted rural workforce. In some areas, this has led to a doubling of wages for farm laborers. Rising food costs indicate that these increased labor costs are being passed on to the Chinese consumer. The story you have not heard is that China is in worse shape than the USA.
