The bigger question is what about the gas station clerks? Or cleaning people? Or wait staff? Or any of the people working the millions of other jobs that just totally suck. Having done it in the past, I'm 100% sure nobody wakes up totally stoked to go bus tables or wash dishes.
So, maybe people who have awesome jobs will just keep doing what they're doing, but for people with shitty jobs, why not say, "F* it, I can get by with the guaranteed minimum, so why bother?"
