A KEY unperceived problem is that ILLEGALS are only "cheap" labor because they are ILLEGAL...once they are legal and have to be paid like citizens, nobody would want to hire them!
Why hire someone who speaks English badly, if at all, unless you can pay her under the table and she cannot complain about being used?
BUT then, we would be stuck with them-- an enduring albatross of the low aptitude, dependent class. The ObaMessiah and his Left KNOWS this!
We are simply allowing the invasion of the Third World...and they will degrade us into that from which they came...there will be no coming back. Amnesty for 12 million would soon mean 100 million net new poor and culturally disparate.
