errr, yes, if wading hip deep in illegal immigrants is your idea of growth.
I drove an OTR flatbed for several months, my favorite destination was Mexicali. Here you made sure you pulled every light bulb and reflector from the trailer you were dropping off, left your truck running and got the hell out before the mexicans stripped the chrome and mirrors off. I'm amazed at the number of people on this thread that don't understand that 80,000lbs of un-inspected 3rd world truck coming down the highway at 70 mph is....errrrr.....a bad idea. Your trust in the us government is misplaced......
I am sympathetic to your concern that American drivers do not have access to Mexican roads. From my understanding, it is not safe for Americans to drive rigs in Mexico. The lack of access may be a way to oppose this agreement without triggering unilateral tariffs from Mexico.
I am not sure if this issue affects illegal immigration. I am in favor of inspections to ensure that immigrants are not smuggled.
In a broader sense, NAFTA was supported to decrease illegal immigration. I am not sure if NAFTA has had an impact on illegal immigration. On balance, I think that illegal immigration would be worse without NAFTA. Perhaps there is evidence to the contrary.
