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.
I see this definition of communism more lately, but the dictionary definition of communism absolutely does not rewards based on work. It rewards based on need. To the point where money can be abolished altogether. What you describe sounds like socialism, where the distribution of goods is based on contribution, rather than need.
I feel like a lot of discussions surrounding communism have this issue, where people do not have the definition of communism aligned properly. Where did you learn your definition of communism? And where can one read about it? What I have been taught aligns very well with Wikipedia.
