It’s easy to see how that falls down though. If everyone’s in it for the love of the game then lots of people are gonna want to be up on stage, like Taylor the superstar, not cleaning the outhouses like Bob the maintenance guy.

And people will say Bob is being exploited, of course, but Bob did choose to take that job. Of course Bob needs to eat and to pay rent and pay for health care and entertainment and to send his kids to university and all that. But let’s assume we take care of all those other things Bob needs the money for, would it still be exploitation if Bob was willing to accept some amount of money (less than what Taylor gets paid for the concert) to clean the outhouses?

I don’t think so, and I doubt Bob would either. I think he would be unhappy if his choice to accept payment for that job were taken away. I think Bob would say the job doesn’t bother him as much as other people and that he benefits from having a stronger stomach (or a weaker sense of smell) from everyone else. Just because we find the job intolerable and disgusting doesn’t mean Bob does. And that’s one of the limitations of empathy (which is so often brought up in these discussions).
