What has happened to wages and employment since NAFTA went into effect?

The San Antonio Express-News had an article on this in today's paper called More jobs, higher pay in years after NAFTA. I highly recommend it, probably because I wrote it. My comments were in response to two articles by Carlos Guerra. The links to his articles are in the article. My basic point is that wages and employment have done well since January, 1994 when NAFTA went into effect.
