Some very valid points being made here by Mercer and B40-8. I agree that the "issue" of immigration is in essence a diversionary tactic. It's misdirection, backed by the federal government to keep average citizens from realizing where the real trouble lies.
Take garbage collectors for example. A garbage collector might make 43,000 a year. An NBA star like Kobe Bryant makes 23 million a year. Suppose every NBA star took the year off, what effect would that have on the health and safety of the average american? Now suppose every garbage collector took the year off, what effect would that have on the health and safety of the average american? The spread of disease it would cause? Impassible streets from garbage? Unclean water supply from the run-off? How can the value of certain work be allowed to inflate so recklessly? My perception is that there are many issues citizens of the U.S. face which are much more relevant than "did bob the gardener get his green card or not?"
