Eeh, honestly, if I'm either high up enough in a business or own my own, if someone does work, then they get paid; simple as that. Do better work, get better money. I mean, if they're "work study" kids, then I might not pay them as much as college kids looking for credit and something to actually help them, but I'd still pay the former, because I'd still ask them to occasionally participate. Why? The same reason some professors leave "unsolvable" problems on their blackboards for students to have a crack at: you never know who might come up with some genius, novel solution to a problem that's dumbfounded several experts.
If a work study kid managed THAT for me, I'd get the motherfucker a car or something.
