One answer lies in the contrast between the united states economy and china's economy.

America's economy is extremely regulated. China's is extremely deregulated.

This leads to american businesses paying far more on taxes, safety, environmental concerns, unions and a host of other expenses than equivalent chinese enterprise. There are considerably greater regulatory impediments in the form of red tape and regulations which american businesses must contend with which chinese businesses do not. This hinders business in the USA, while giving chinese a big advantage.

It illustrates one fundamental reason for the USA's economy being stagnant and contracting while china's economy has grown at a high pace.

+1 example of deregulation being an advantage.
