Slanted charts and graphs on a subject you know very little about is hardly what I would call documenting your case with sound economics. I see the benefits of NAFTA everyday in a much more tangible way than most people and I associate with a lot of other people that are in similar business's doing work in both countries. I actually know the facts of why we work in Mexico and the U.S., the facts of how it has affected employment and wages here in the U.S., and where we would take our business if NAFTA was taken out of the picture (yes we actually talk about this kind of stuff). As I have said in a couple of other replies, learn what NAFTA really is, the zero tariffs (no tariffs in some cases, there are still imports that are not exempt under NAFTA) between the USA, Canada, and Mexico are not unconditional. It really is a good deal for the USA.
Lots of people want to blame NAFTA for their problems when it is one of the few things that actually works well.
