Mexicans do not pay taxes---period! They won't here, either. They will, however, collect everything allowed after "amnesty". Along with the millions of relatives they'll now be allowed to send for.
Why would we want to allow the creation of another divisive entitlement group with special rights in this country? They shouldn't even be talking about amnesty without offering a return to Constitutional govt.
I read somewhere that the 'record' for extended family that one anchor person was able to bring into the US stands at 150.
You can bet your bottom dollar illegals, when given amnesty and the right to vote, will overwhelmingly pull the dem. lever.
