The Korea Free Trade Act

My friend Mike Tuggle has asked me to post a link to his article "Stop the Korea Free Trade Act."

Is Free Trade a good thing or a bad thing?  I'd like to hear opinions on both sides.  Long ago, when I took economics in college, my conservative professor said that free trade is a good thing, allowing various countries to concentrate on the goods and services at which they are most efficient.  Also, the South was pro free trade before the war between the states and the North was against it, hence the system of tariffs that so punished the Southern economy.

So why is this situation any different from that?  Mike explains at the above link.
