There is also the case of the 'outcast' skills which are currently stigmatized. Unless there is a literal caste of people stuck doing these jobs they tend to ironically have to pay better. Porn actresses get paid in part for the 'reputational damage' as even today people are deeply silly/stupid about past work. Skilled labor in terms of "needs many years training" outcast skills are practically a hypothetical, and are what I would call 'high entropy' in the sense that it would take a lot of work and rare combinations to achieve. Practically an exercise for science fiction writers to depict say, a society where say heart surgery is viewed as deeply shameful yet still managed to perfect the art of heart surgery anyway.
