"[T]here is plenty of money for more fencing. Americans love their fences despite the fact that this tactic has been shown to backfire. Physical barriers don't just keep people out. They also keep them in. Immigrants can't return home during those months when they're out of work, or to visit mom for Mother's Day, because they're afraid they won't be able to get back. You build more fences, and you wind up with more immigrants stuck on this side of the border. Good plan." - Ruben Navarrette, Apr. 16, 2013.
