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.
Your personal motivations don’t represent any society, at large.
Your premise is that people only choose jobs because of the salary? I reject that premise. All information I’m aware of tells us that most people choose jobs because of aptitude, interest, skills and prestige, not because of financial concerns (given that all jobs compensate equally).
It should also be noted that communism doesn’t mean uniform pay. You need to go back to the drawing board and rephrase your question.
Also it’s absurd to suggest that capitalism rewards dangerous jobs more, when it clearly doesn’t. Your example is terrible because power generation is heavily regulated and very safe. The most dangerous jobs are extraction or harvesting jobs, and they can be high paid…but are not well paid in the most dangerous circumstances.
