The subject of one North American currency surfaced shortly after the passage of NAFTA in the early 1990's. The originators of NAFTA expelled the rumors of a single currency as a nothing more than conspiracy theory. The reaction to someone who mentions something that is underhanded or sneaky is immediately labeled a conspiracy nut. Since no one wants to be labeled as a paranoid kook, the subject is usually dropped like a hot potato.

Granted, many theories are far fetched, but some are not.

I find it odd that Ross Perot was labeled a kook when he said that NAFTA would result in the loss of millions of American jobs, after he used the term "giant sucking sound". Well, after the architects of NAFTA label his comments as being nothing more than a conspiracy theory, the so called "theory" has become a reality.

Comments by Ross Perot regarding NAFTA, jobs, immigration, and the decline of the dollar.

Here is an interesting piece by Chris DeLong, Brad DeLong, and Sherman Robinson, Titled, NAFTA and Jobs: Remember the "Giant Sucking Sound"?
