Seeing people like you getting hunted and snatched up might not be concentration camp terrorizing but I'd think that the average illegal, the guy washing dishes or picking fruit are just simple folks, not used to that sort of treatment.
You're right about them not being serious, problem has a very simple solution, fine anyone who hires them or is found to be hiring them. I keep telling my buddy with work visa (or whatever he has) "Americans are useless, country would collapse without all of you, don't worry about it" But that was a few years ago, he should probably worry about it now.
