Here's a little something interesting that I recently found out. My area has a sizable amount of Spics, and I have friends that are "in" so to speak with School districts and PTAs etc. and I recently found that enrollment, especially High School enrollment, has decreased quite a bit from last year. The running and obvious theory is many of the would be students are either illegal or their parents are illegal and they don't want any records anywhere the government could find it for fear of getting caught. In theory they could also be self deporting but I find that unlikely, and ICE has not done enough in my area for me to think it's from forced deportations either.
I doubt my city is the only place this is happening, so we are about to have a school year where thousands if not millions of poor(in the financial sense) teenagers are going to have nothing to do. The common problems with illegals in most people minds is crime and "job theft" and this problem is probably only going to get exacerbated by this fact. This may not be a bad thing as it will probably increase peoples desire for deportations and thus accelerate them, but the actual effects of illegal immigration are probably going to get worse before they get better.
