so you're fine with businesses that compete against you hiring illegal immigrants? After all, hiring an undocumented worker is really only a crime because the government says it is. If a company can find cheap labor willing to work for less than minimum wage, why should the government be able to tell you what to do. Right?
Don't forget about companies that refuse to pay overtime/holiday wages, or companies that pay cash under table(to keep from paying taxes, insurance, workman's comp, etc).
