Do you live in a border town? I do and I have experienced first-hand how rampant illegal immigration is wrecking our economy and the social fabric of our culture. Our hosptials are closing down becuase they cannot afford the emergency indigent care that illegals are entitled to and we can't afford the free schooling, not to mention the breakfasts and lunches, that their children take advantage of. Additionally they refuse to assimilate because they are not leaving their country because they are persecuted and see America as an opportunity for the fulfillment of their dream to be free, but rather as a teat to exhaust before running back to their home country.
I live in Houston Texas... I have also been to the border towns quite a bit. but you just reinforced my point. If they become documented then they will be paying for those services they suck dry.
