Your posts show you have no clue about the Chinese culture and their manufacturing capabilities.China has built a false economy based on the sale of cheap crap. It's not a good foundation.
Many Chinese factories produce very hig quality products. The have upgraded to leading edge technolgy. If the manufacturing moves to the USA, it will be a challenge to US manufacturers to build high tech, efficient manufacturing facilities and train the workers to use them.
The middle class of China is equivalent of the lower class in the USA but most are happy because their living style has improved in the last 30 years. They are not as spoiled as the US citizens. ou have to admit we are spoiled.
