Are there some shitty jobs that don't deserve higher pay because of the value they contribute? Or do you see that being a business that shouldn't exist? So let's take a sewer company or something. Or any maintenance position where it's not clear there's a dollar value on the value being produced.
For example, restaurant probably aren't possible if waiters and back of house are all paid 30/h.
I'm mostly trying to understand what you're really trying to get at. I don't think its possible for all jobs to be equally paying or be equally good - there's always going to be inequality there. Unless you're arguing there shouldn't be shitty jobs but there's literally always going to be shitty jobs in any society and economic framework you spin up.
Society will still need people who perform maintenance on sewers, do construction, clean building etc
