I might add...we're quite LUCKY that we don't share a common border with Mexico (and thereby the rest of Latin America), as you do. If we did, the flood of illegal immigration into this country would be like a tidal wave. It would be one hell of a big problem. I have no idea what would need to be done in such a case...but it wouldn't be any easy thing to "fix", that's for sure.

With countries...as with businesses...location can be everything.
