And not just there, but all the other emerging economies that are trying to industrialize. They would all have to follow the same system. South East Asia, Africa, South America etc.
Now I'm not saying that the income of workers in China is not going to rise - I'm saying that at the moment, there is a big difference, and that gives them a competitive advantage. In china you typically have 3 or more people serving you at one table when you go to a restaurant. That would not be possible in the west because of the high labour cost - in China it's possible because of the wage difference between what is being earned in the restaurant and what the workers earn.
Controlling your economy and only buying local goods is not a good idea in my opinion, but when there are new manufacturing processes being used in emerging countries, then you have to be aware of this.
I don't believe in protectionism at all, so that's not the point I'm trying to convey.
