From your comment, I presume that you think NAFTA is a bad thing. One would think that after ten years, there would be some evidence, such as wage or employment data that supports your position. Please spare us the stories of Uncle Joe losing his job at the toothpick factory. Thanks in advance.
Actually, I think NAFTA will bring about global wage parity which is a good thing. The problem is that the US worker doesn't see the writing on the wall and is not retraining. That's going to be expensive for those of us who are taxpayers.
So you wouldn't consider the perpetual extension of unemployment benefits a sign of what NAFTA is doing to our economy or the exponential increase in debt of the consumer or the exponential increase of our trade deficit or the exponential increase of government outlays for social programs as signs of what NAFTA has done to the US economy ?
Step away from the crack pipe, dude!
