You're right, Jerry--it seems to hinge on whether somebody perceives that his or her job is threatened by illegal immigrants--or can imagine a scenario where they would be competing with illegal immigrants for the same jobs. But legal immigrants would offer the same threat--and supply and demand means that the immigrants will come here, legal or illegal, regardless of the outcome of this particular bill. In fact, if someone were concerned about pay at the lower levels, I would think they would want the immigrants to be legalized--that would lessen chances of exploitation--and raise pay for everybody on the low end of the economic scale.
