Fixed that for you.
Look, people hire illegals because they make more profit from it. All we have to do is make darned sure they don't make ANY money and it's no longer good for them.
I'm talking everyone. If a farmer uses illegals to pick their apples, identify them and let those apples rot in the store until the store stops buying them. If a corporation uses a window washing company that employes illegals, picket them. Carry signs that say "This company steals your tax money by hiring illegals" watch and see how many people will turn around and go elsewhere.
