Read post 33 again. It operates outside the law. Illegals are harmed by lower wage levels by all accounts and in some cases substandard working conditions. Taxpayers are harmed by assuming costs which properly belong to employers. Society is harmed by tolerance of a 2nd economic construct, not bound by our legal system. It's no different than undeclared cash compensation. If growers can't pay more, which I doubt since there are growers who use legal immigrant labor, they may well go out of business.
So this is conservatives saying what we really need to solve this problem is better laws, more regulation and more taxation :~) LOL
