"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?""

That'd be a good thing. People leave the bad jobs behind, which would either free up room to automate them without social consequences, or the job would have to be made more attractive in some way (shared between multiple people for less stress, better pay, etc...).
