The illegals will go home. Businesses will hire American workers at a decent wage.
This is also the answer for idiot bush apologists like michael medved who cry "what are we going to do, round them up and put them in concentration camps!?"
No this is 180 degrees back-ashwards. Destroy companies who hire people to do work, because they don't have the wherewithal to do the job the INS refuses to do. Yet, make it illegal for government workers TO EVEN ASK if people receiving free medical care, housing, food, college degrees etc. are in this country legally.
Get a grip here people. Hiring someone to do work is not the problem. It is free government services that attract the destitute here like flies to honey.
