I never said anything about not being responsible for my own career. There was a previous implication that we need to help the boss look good, which is BS. If I want to develop myself because I want to explore different options or expand my skill set, I am free to and generally opt to do so. If a manager wants to develop my skills, then that is their responsibility.
Again, let's not shift all the accountability to the guys lower on the ladder. It's a team effort.
Perhaps I just don't understand your mindset because I do not define myself by my career. Work is just how I exchange some of my time and effort for money so I can focus my life on the things I actually matter to me, so the "weight" of my career is perhaps different than yours. Which is fine, btw. I don't really have any issues if someone wants to make their career their life, but I'll never align with that, especially not at this late in my adult life.
