I know of a few downsides but the current article make it seems like a tech paradise.
* pollutions
* the # of people graduating college doesn't imply that the quality of education in China is the same as USA. I've heard stories and my ex went to China to study abroad and cheating is rampant. It's mostly rote learning.
* the stock and IPO he've mentioned make it seems like China stock market is awesome. I've played around with China stocks when China started to trade. Let me tell you, there were tons of pump and dump and companies lying on their balance sheet. An example was JRJC, CAST, CCME, etc.. It's hard, very hard market.
