Send a few home in a bag. Maybe they'll get the hint.

I'm being facitous though. A lot of immagrant workers perform jobs that natural born Americans won't bother rolling out of bed to do. I think it's a mistake and an injustice to provide them with social services unless they have become citizens. You've got to give a guy credit who's willing to leave his country to come here and work. But, you've got to give a guy the boot who's coming here to leech... Offering free services is going to attract leeches.
