That's mostly because our industry is a bit of a mess. We clearly have different people doing completely different roles that are in the same career ladder with the same title. Forget on call, some folks with the same titles and same salaries often do easier or harder jobs. That's a separate problem.
Salaries in the industry have a lot of expectations baked in, like the expectations of being able to learn and train yourself without the company having to pay for it (aside the occasional paid book). Being on call is another. That some folks can get the same pay regardless of their responsibilities or how hard their job actually is is, indeed, a problem.
