"I am not a fan of Michael Walzer but IIRC he argued that jobs that are 'dirty' (like coal mining) or disparaged (like cleaning) should either be shared kind of like jury duty or should be generously pensioned."
By all means shared. If everyone has to do a little bit of a "dirty" job, chances are that we are more likely to figure out how not to have to do it or how to make it more palatable.
