Factory replaces workers demanding higher wage
How long before the factory simply leaves China? If local governments come to reality and begin to understand that corporate taxes are a failure, and reduce them to zero, all of these factories would simply come back to the country using the product, lowering shipping costs, and reducing inventory needs. Until then it may pay for a business to manufacture products in China or elsewhere.
For China this means serious problems. The country is not wealthy enough to weather this easily. This will prove a difficult time.
