I think that is very difficult --- all along the border you see them come over --- many times not to work but just for the health care --- and they are not expected to pay a dime but yet a middle class American taxpayers who have always paid in --- even to a very costly county hospital --- will not get even a discount.
However, on any given day, you can walk into Thomason's ER and you will see a scene much like the one described in this article.
