Some yeah, but undoubtedly not enough to keep it working. For example i doubt that many people enjoy working at garbage disposable or basically any waste disposal. Of course these jobs should be fully operated by machines. Or any assistant jobs in manufacturing or jobs that operate in shifts.

I daresay there's a few people out there who might enjoy going into the sewers to manually remove the fatbergs, but probably not enough.

I was also thinking that. As an example, retail work seems to me to be a kind of hell I don't think I'd want to endure. But I know people that really enjoy it. So it's probably true of any job you might think is only done by those that are forced to.

I think, if AI and robotics replace most jobs. After some years of pain when capitalists enjoy the infinite money glitch they've discovered, there will either be a revolution or a natural coming to understand that things need to work differently.

Now, understand this would only work if the vast majority of work could be done via automation. In this case the vast majority of people would be able to pursue what they enjoy, a bit like the star trek anti-economy. If all remaining required jobs were no longer filled by those that volunteered to do them, there would be some kind of draft (think like jury duty), where people able to do a job have a chance to be called in to do it for a few months then released back to pursue their own interests.

I've always seen capitalism as the carrot on a stick we need, when we need human productivity from the vast majority of people. If that's no longer the case, it's not a suitable solution and all the ideas like universal basic income are just stopgap measures to try to eke a bit more time out of the capitalist system that has already run past the point where we can keep enough people usefully employed to make it work. That's almost certainly the reason we're seeing the huge wealth disparity that increases. As the productivity per person goes up, all the increased value only ever rises to the top.

Bit of a mini rant there, sorry about that.

Going into sewage vats and breaking up solidified waste and oil clogs

Deep sea oil rig repair

Underwater dam repair

Driving public transportation (not enough to maintain a system)

Elder care (there is a worldwide lack of people willing to clean up piss and shit of often angry, sometimes aggressive people and deal with regular loss for bad pay, much less in an ideal profession freedom world, relative to the amount of people needing care)

Forensic pathology is something that very very few people enjoy also, but is very needed.

Urine farmer (hunting luring, sprays for animal repellant)

Coal miner

Any precious or rare metal or stone miner

People love intellectual jobs, creative jobs, and some public service jobs. It is much much harder to find people to do body-destroying terrible-condition manual labor jobs. Ideally those are the jobs to be replaces, but of course capitalists want to replace the former category of jobs because those cut into their profits more.

I build rockets that go on satellites and scientific missions. I enjoy my job; I find it extremely interesting and often quite fulfilling. In the grand scheme of things, I really wouldn't change much. But like my boss said on the first day of the job, "This job is awesome, but it's not worth doing for free." If you told me I could still enjoy the same level of comfort at home that my job affords me, but I wouldn't be paid, I would quit. I'd rather be at home reading, spending time with my family, playing around with my hobbies, etc.

My wife is a nurse. She loves her job, but she wouldn't do it for free either. Her love for the job prevents her from quitting when she's abused by the public for 12 hours, the pay makes her come in.

Some people are motivated by enjoyment alone to do jobs for free, but many are not. Or the thing they love doesn't help society in a meaningful way. Or they just don't want their hobby to turn into a job. I don't think there's a big enough overlap to have a functioning society.

I can't imagine anyone enjoying being a correctional officer enough to do it for free. Or waste management (sewage).

Living in a nice society is all the motivation people need.

You might want to read up on the bystander effect. You do the dishes because no-one else is going to do it. But as soon as there are others who can do the job people will just stand around and let other die before they put in the effort.

Sure is a good thing doing this dishes is the most complicated and least-pleasant thing people can do...

Who's gonna volunteer to go through years of training specializing in commercial diving in wastewater to treatment plants for free?

That seems kinda too idealistic view of the world.
I know much more people who, if not directly forced, would let the dishes or basically any environment around them completely mould and break down before even considering cleaning up even just the mess they have left behind, than people who altruistically do clean up after themselves and others.

I do agree that living in a cleaner and nicer society should be enough of a motivation and for some it is, but there's not enough of us.

We can already observe it in many public spaces where trash gets left laying around even if trash cans are available or public bathrooms or showers or my favorite example in the gym where plates get constantly left on the machines and cable attachments just piled up wherever those fell.

Fair point, though i did try to use positive encouragement model to incentice people to work in not so enjoyable jobs. Even if not permanently, maybe in rotation.
