> really achieved what they did elsewhere due to sheer luck/help
This world view is not falsifiable. Regardless of success you can say it was luck.
But I just don’t understand this. In my work we are constantly giving people chances to take on more responsibility, and often they don’t want to, or it doesn’t work out. Why would you expect that you could drop them in as CEO?
Are CEOs always the cause of success or failure? No. Are they good at avoiding blame? Yes. Are they also extremely skilled and competent people? Yes.
You can't drop everyone in that position but there is a significant number that still could do it. It is not 100% more like 50%/60% luck.
It also depends on whether you're providing appropriate compensation for the responsibility that you're offering. I see several cases where managers offer more responsibility for a peanuts' worth of pay hike and then say the same stuff you said.
You know which people are eager to take on more responsibilities? The people who don't believe in the concept responsibility.

In my experience, this means one of two things:
You're asking people who already have too much to do, to add even more to their plate.
Or
You're throwing the projects which are doomed to failure and nobody else will touch at them.
In basically every job I've ever had this has been the case. There is nothing like being given a shit sandwich and being told it's delicious ice cream.
