You ought to visit one of the county hospitals or welfare offices in the SW where many immigrants are --- you'll see all kinds who aren't here to work. The Medicaid rolls are filled with immigrants. In many cities of the SW, you won't find many blacks or whites or hispanic-Americans on welfare --- it seems almost exclusively for the immigrants of Mexico and their children.
I don't disagree with you .. but to me, this also falls in line with the abuse of welfare and all the free programs.
Hospitals, from what I understand aren't allowed to turn away people for ER care. Many women (not just from Mexico) come to this country to have their babies ... Why?? because their babies will become US citizens with all the rights that come with it .. and in this country we won't keep the child and deport the mother
