The Federal Govt has no incentive to stop the flow of illegal immigration. You tend to forget they don't represent the small guy trying to earn an honest dollar. Who they represent are corporations who need cheap labor. The more people seeking work, the more wages are bid down, the higher the profits. As long as that is the case, the corporations are going to continue to ask their government pals to keep the illegal immigration spigot wide open. If you want to deal with the problem of illegal immigrants then deal with the inclinations of corporate capitalism. Anything else is simply a band-aid. You can bitch to Dept of Immigration all you want, even fire politicians over it, but as long as The Man wants his cheap labor, he's going to call the shots. Deal with it at the source.
