It is really very simple, who in there right mind would pay high US labor rates when they can pay low Chinesse/Indian/whatever labor rates? Who in there right mind would buy high priced American goods when they can buy cheap Chinesse/India/whatever goods? This is really all Paul Roberts is saying and he is entirely correct.
Let me see...what company in their right mind would pay wages to an American citizen instead of to the Chinese government (soon to be our enemies I think)? The answer,true patriots buy American (where possible) and hire Americans. Free Trade is nothing more than one world garbage which will lead to a loss of sovereignty for the US and will lead to Rich/poor population. The middle class will cease to exist. Sometimes the cost of buying cheap, foreign goods is higher than you think.
