The problem is not just about the illegal immigrants putting jobs at risk. It is the fact that they entered the country illegally and showed contempt for our laws. If someone breaks into your house and starts demanding things, would you give anything to them? There are many who come into our country legally, how would it be fair to them if we give illegal immigrants a pass? That shows weakness in our resolve to enforce outlaws. The results will be more people entering the country illegally. That can pose a lot of security risks.
