I wish that were true...
The fact that the Chinese don't make anything we can't do without or make ourselves is, obviously, true. Once again, they don't sell us food or energy.
...we have closed down so many factories...
Correct. Thousands of factories in the US have closed to avoid high labor costs and regulation. Those factories and the jobs they represent went to China to take advantage of cheap labor and no regulation. This was encourage by granting China MFN status. The solution is easy. Get rid of big labor's stranglehold on industry, this is happening now. Revoke China's MFN status, you cannot have free trade with a country whose wage rates are a fraction of yours. Finally, a wholesale change in government that, basically, closes down the EPA and the Department of Labor.
...we are not allowed to extract natural resources...
And that, sir, is an utter crime. Politicians who block citizens from reaping the wealth that lies beneath their feet should be expunged.
That has already happened. Do you know the percent of the PRIVATE sector workforce that is unionized? I'll answer for you, it is less than 6%. So there is a 94% chance that the jobs outsourced were NON-UNION.
