I'm fully aware of what you're trying to say but the law is the law is it not? You seem to be implying illegals can do what ever they want, enter illegally, use phony documents, lie continously but because no one in the hot sun of Texas supposedly wants to sandblast we should look the other way.
Don't you think the proponents of a guest worker program would have a more legitimate claim we need these workers if the law was enforced and illegals sent home first? It would be clear at that point with the economy collapsing and all how badly we must have them around.
Its not an experiment, those in govt know exactly what will happen. They have staticians, analysts, economists, etc. They have the Dept of Commerce, the Federal Reserve Bank, etc. This is their source of facts.
You, on the other hand get your facts from VDare, World Net Daily and Free Republic.
