Tango – nevertheless the money is going into the US Treasury. Even if the ID is fake, we’ve still got the cash.
Please note that the industries with the greatest illegal problems are things like meat-packing, where the work is hard, dirty and dangerous, and the employers don’t want to pay the going wage to get American citizens, so they “have” to resort to immigrants.
Ask the farmers whose crops rot in the fields because they can’t get enough red-blooded US citizen workers to pick them.
