I put the salient part in bold. As I've said elsewhere, one problem with illegals is that they give employers an incentive to keep their salaries off the books. I mean, what tax ID or social security # do you put on the W-2 or 1099 for an illegal? And when salaries aren't reported, taxes aren't paid - either by the employer or employee. So guess who ends up footing the bill for the lost tax revenue? Why, the poor sap who actually obeys the law - the middle class.
That is a HULLUVALOT of money that went into the UNDERGROUND ECONOMY.
