I like Paul Graham's essay where he points out that society can adapt to not have these things.
He uses the example where people used to have live in servants. Now people aren't willing to be butlers so the wealthy just go without.
A similar job would be hangman or executioner. If everyone decided not to do that job, then it wouldn't get done. Is that really so bad?
Janitors are quickly being replaced by passionate iRobot employees. Cashiers at the stores I shop at are replaced by self-checkout robots made by passionate robotics people.
Assembly lines and making clothing...... do I even need to say it?
Construction jobs should go unfilled, it's shitty work, why not leave it unfilled? Who cares? Soon enough those quad-copter construction workers will build stuff anyway.
The medical profession is full of passionate doctors and society will adapt if we truly run out of proctologists. Many dental visits would be unnecessary if people used proper preventative dental hygiene. Society could cut back on the suicidal dentists and be fine.
If a job would truly go unfilled due to lack of passion I doubt this would be a problem.
Also, every single job you listed, I guarantee there are people who thoroughly love those jobs.
Some people are passionate about making money and those people would be passionate about being a highly paid prison guard or executioner or butler. This is, in fact, pretty much what happens. People who love money a lot do become dentists and they do enjoy their job because it affords them their yacht on the weekends.
Passion for money is genuine passion.
