You missed my point. Much of the angst and rhetoric is being directed at people whose families have either been here longer than the people complaining about them or they are people who have already done all that was expected of them to become good honest hardworking American citizens. For example, take the two items I posted earlier today about James O'Keefe releasing supposed 'expose' videos showing 'foreigners' either voting illegally or who were planning to vote illegally, yet in the two cases which he made a point to dwell on, the individuals involved, while they may have had foreign sounding names and I assume that they may NOT have looked like lily-white O'Keefe, they were nonetheless American citizens with every right to exercise the privileges of that citizenship yet O'Keefe was attempting to make them the subject of another one of his outrageous 'ambush journalism' witch-hunts that have been encouraged and given open support to in the past by Wingers and people like Faux News.
As for your argument about not needing low-skilled immigrants driving down wages and taking away jobs that 'Americans' should have, you're starting to sound like my grandfather whom I can still recall going on and on about when he used to own his own company back before the war how he was expected to hire no-good lazy drunken Irishmen who had come to America looking for a free ride.
