If you have to question what trade has to do with illegal immigration then you obviously are forgetting the line of BS we heard from the Clinton's et al about all the "benefits" we'd derive from NAFTA. They lied about our trade balances with Mexico( a healthy surplus has turned into a steadily rising deficit), how it would decrease illegal immigration by creating so many new jobs for Mexicans ( even want to touch that??), plus all the new jobs it would create in this country( an even bigger joke).
The point is this so-called trade agreement created a parasitical relationship between the US and Mexico that now has evolved into a sociological nightmare for healthcare givers, educators, prison officials, etc. Sorry, you just can't focus on one or two aspects of something like this to determine it's impact.......one has to look at the entire impact of NAFTA, CAFTA, etc. on our society to determine it's value.......and so far it's a disaster. If you don'tunderstand that you being disingenuous at best and delusional at worst.
If that is the case, could you perhaps direct me to the NAFTA provisions concerning (illegal) immigration? You don't have to wade through thousands of pages as an earlier comment suggests.
