Currently I would say over half of the illegals I know have self-deported.
The dollar is dropping daily and the peso is worth more.
Once the peso gains more on the dollar, it won't be an advantage to leave all you know, cross into a country that doesn't want but will use you, pay an outrageous sum to be smuggled over, work at a job that an "American" wouldn't do, for less money because you are scared, try and learn a language but have no one to really use it on because you are too scared to go outside of your "comfort zone" of little mexico, haiti, guatemala, etc, be stereotyped as a worthless scum sucking drain on society because they look foreign (what about those that aren't illegal but look foreign?).
I live in TN. Been here most of my life. Contrary to popular belief in regards to Tennesseans, I am educated, world traveled, don't ride a mule, am not pregnant (actually waited until I was 26 to breed), and usually wear my shoes.
If people would stop looking at the mass of humanity and try to see the individuals within it, this would be a better world to live in. Try some tolerance people and educating yourself on the facts on both sides would be a novel change.
