LOL! If you go down to the port you can see them loading all those jobs into 40' containers. Do we export more or less today to Mexico and Canada then we did before NAFTA? How much? Did you know that real wages fell in the 10 years prior to NAFTA and increased in the 10 years after NAFTA? Did you know that manufacturing jobs increased for seven years after NAFTA passed? How is that possible? The only denial here is coming from you.
If you go to Ohio, Upstate New York, Indiana, Pennsylvania, Michigan etc., you can see the empty factories-ghosts of the more prosperous times in American...before free trade, globalism, credit derivative crap etc...so yes Nafta did cause job losses....many job losses.
