> how much money would it take for you to go scrub toilets
If my needs were otherwise met, and there were clear instructions allowing me to do this in confidence that I wasn't inconveniencing any users of the toilet, I'd do it free. (Cleaning a toilet is less messy than changing a baby, and that's not hard either.) Given proper PPE, I'd do even more "disgusting" jobs, if they were jobs that needed doing: I draw my line at cleaning up sharps, but that's only because I'm not trained.
Maintaining communal infrastructure is not a thankless task: you can know that everyone who uses the infrastructure until next maintenance time benefits from your work, which is more than most people can say about their jobs. There are people who take pride in their work, even if you consider that work low-status, and beneath you. Do different work, then!
Do you really think most people would live lives of idleness, if not compelled to behave otherwise? If you saw something that needed doing, and you had the means to do it, would you just… walk by? If I may, that says more about you than it does about anyone else.
Quite the strawman there. Not wanting to work [at times literally] shit jobs without excessive compensation, is not the same as everybody being idle. I can list thousands of things I'd rather do than clean public toilets, and I don't even do thousands of things! Though yes - I do think a huge chunk of the population would be generally idle, if possible, in terms of commercial productivity, and I see nothing wrong with that, besides the fact it would crash any economy where it was possible.
