What they forget is that once the illegals become Americans, we will need more illegals to do the work Americans won't do. And then we legalize more illegals and make them Americans, and then we don't have illegals to do the work Americans won't do and then we legalize more immigrants to do work Americans won't do, and then ....
Vicious circle and few seem to get it.
Ding ding ding.... we have a winner!
