I believe that many illegals would prefer to work here tax-free while reaping the benefits and sending remittances back home. The idea that they are going to work unskilled jobs to fund the retirements of elderly Americans and freebies for gibsmedats is laughable to them.
As another FReeper pointed out, illegals are the last “free” people in the US. Our latest new “tax” (ObamaCare) doesn’t impact them at all; monkeying around with Social Security to keep it solvent doesn’t bother them one whit either.
