I understand your position, and it is a good and fair position. I would only say that the economic forces at work are a far different problem from basic border security.
Keeping wages artificially high by not allowing competition is a bubble that will inevitably burst, if not from this cause, then from some other. If the quality of the work is the same or higher, for the same or lesser wage... then the processes that will pop the wage bubble are already in place. Immigration, in such a situation, is a symptom not a cause.
But I'd really like to keep the topic on security.
Considering the 19 9/11 hijckers had 64 drivers licenses between them, do you favor allowing illegals to have drivers licenses? YES OR NO?
