I think we're taking the extremes as the norm, and it is clouding the argument. Let's just say there is risk on both sides, nobody is entitled to anything except the chance to receive remuneration that is deemed fair, whether that's through investment or salary.

Your last point is the most interesting, though, coal-miners were paid very well and by contrast I know (good) developers that earn less than the national average. I am not arguing (in this case) about software developers, but all employees from all backgrounds.
