Frugal,
I'm glad you are so up-to-date on cause and effects of NAFTA. Since you have only done a 180 view of NAFTA, below is a website that will provide you with the other 180 view from the other side. You will see that the Congressmen who voted in favor of NAFTA never read the document in its entirety. If they had, it would not have passed in the form that was voted on. As you will see, NAFTA has bombed on its original promise of providing a higher standard of living in US-MEXICO-CANADA. It has allowed outsourcing of our jobs and United Airlines is a big participant. The unions aren't the only employees that have been affected, nonunion jobs have also been outsourced. NAFTA has affected food safety and medicines imported to the USA. Those who have worked for 20+ years, and then their jobs were outsourced, have seen their retirements either completely disappear or severely reduced and dumped on the federal government at diminished returns and now companies want to dump retirees supplemental health insurance altogether. If you check the link below, you will see that NAFTA has been a boon to offshore investments thus being able to circumvent US regulations. Check out Dubai in United Arab Emirites. Dubai is becoming a huge financial and corporate center in the global world we live in. Haliburton has already moved to Dubai and other US corporations (banksing) are also moving there. Dubai has mushroomed into an Emerald City of OZ since 2005 when it began construction and rising from the desert. NAFTA was a pie-in-the-sky solution for Wall Street investments. Corporate profits certainly enriched corporate CEO's who are laughing all the way to the bank. If you look closely, you will see the subprime real estate mess. Oh, as another side-effect, the US dollar has crashed against the Euro. That is why fuel prices have soared. Believe it or not, there are foreign countries who want to destroy the USA as a superpower and they are now in control of the money. So, Frugal, defend NAFTA if you like, it has not accomplished what was promised to the American people. On the contrary, just the opposite has happened.
