China does not officially decline a "middle class". Unlike US, you can see very extreme living condition from one city to another city in China (evern these cities are only separated by 3 hours of driving).
In some places, you would see a Nike store selling US$200 sneakers while the salesman only get US$450 salary. But then, you can easily buy lunch for US$1 in those places. Just want to give you guys some examples that not every places in China is well developed. And it takes time for Chinese government to get everyone up to the same level.
Always looking for Anfernee "Penny" Hardaway!!
