Proof?
This argument can go back in forth… You say they have paid 9 billion in taxes… I say that they don’t pay into the tax system, nor does there employers have to contribute into Medicare, social security or unemployment. I don’t know the $ amount, but how many dollars have been spent on them in public assistance and other forms of assistance without paying into the system?
EDIT… I just read an article posted by the center of immigration studies from 2002 that said Illegals cost the US government 26 billion dollars, while only paying 16 billion in taxes.
