Under capitalism, a lot of the time, highly dangerous jobs are also highly paid. Kind of a balance that the individual decides to engage with. Same idea behind getting an advanced degree in STEM or law. I think of my job by example, I’m a power plant operator at a large combined cycle plant. No fucking shot I’d be doing this if the pay wasn’t good. I’m around explosive and deadly hot shit all day.
Im not saying that nor advocating communism, im just stating that what you said about the reason you think people only do those jobs, I believe at least, is false simply by counterargument. Ask any one of the people who enjoy that kind of work environment if they would ever work in an office, closed in a room seated at a desk all day, and most would probably say you couldnt pay them enough to do it. To them, even if you DO give them more money, its not a reward/compensation because they value different things.
Im one of the office-type people. Id like to think what I do has value to society, and I believe I would do it regardless of the compensation/regardless of if I got the same money as a lumberjack, because I enjoy it. Thats another angle: if everyone is paid the same, why not do what you enjoy. If what you enjoy is being in the woods cutting trees, or on a boat in the sea, or in a tower in isolation for weeks (fire watcher), or any number of other “undesirable” jobs, and youd still get paid a living wage for doing that, same as everyone else, why would you ever subject yourself to something miserable for you, for no better reward?
