I hope I am wrong, but it seemed shady and abusive. This is just modern immigrant labor procurement. You get nasty fines for hiring illegals directly. Instead you hire a fly-by-night company with a bus to recruit them and attest to having checked all the paperwork. When INS shows up, your hands are clean. No more abusive than the old way, just more middlemen involved.
