The definition of free trade and what currently exists in America under the banner of free trade are not the same thing.
Here's what Duncan Hunter has to say on the subject -
"Keeping American Industry and Jobs in the U.S. “American workers are the most productive and innovative labor force in the world. Unfortunately, they are asked to compete in an unfair environment against other workers who make only a fraction of a living wage and are employed by companies that face few, if any, responsibilities to the environment or the long-term prospects of their employees. Our domestic manufacturers are forced to compete against foreign companies that benefit from their country’s currency and regulatory regimes. Ominously, China is cheating on trade and using billions of American trade dollars to build ships, planes and missiles at an alarming rate while, at the same time, taking millions of American jobs. I will reverse this “one-way street” with a new policy of fair trade for the American worker."
And yet we still manufacture far more than any other nation and enjoy 4.6% unemployment and a $13.5 trillion economy. Obviously, we're doomed.
