Something that may have been missed in this equation: The folks who are in your country illegally have found work (mostly honest, just like the rest of us), places to live and things to do to keep below the radar of your country's laws--else they'd BE discovered as illegal aliens. If the folks are already there and doin' OK, hell, they are enterprising and eager for work--something there ain't enough of in Mexico--and very much like any average American.

Someone I know (dead now) was asked as the last question on his citizenship test in Canada, "What's is the biggest river in Canada." His answer was, "The San-ta Laurenca." The reply from the exam officiator was, "Spoken like a true Canadian. Welcome to Canada!"

The two paragraphs relate somehow, I think.
