There's another thing that has to happen and that is for the various states to deny the social services to illegals. When I hear the caterwauling about how much it would cost to round up and deport illegals, no mention is ever made of the billions it is costing us NOT to do it. Tucker has it half right here as far as employers go, but, not surprisingly, fails to address the issues of health care, education, incarceration, etc. which taxpayers are being forced to provide.
Since the feds won't fulfill their obligation to control the borders, maybe each state should be able to set its own policy and give local control over spending on illegals.
The illegals send about $15 billion (with a B) back to Mexico each year. That's another figure that's not usually mentioned when the cost of illegal immigration is discussed.
