I think many people believe this, but how do they know? There are ~7 billion people on the planet. You mean to tell me that only a "handful" are capable of doing a particular job? And not even "CEO of billion dollar company" but "Director of a 200 person org who attends meetings and makes decisions." Really? Only a "handful" of the 7 billion people on earth can do this?
There's only so much room at the top, and you need to spend time near the top to get everything else. Truth is, the everything else is a big part of the package.
I truly believe I could do the job of my grand-boss 4 levels above me on the totem pole, and so could most of my peers. The reason I'm (or someone else is) not there comes down to things like timing, luck, who got where first, and just the reality that one person already being in that SVP position simply blocks everyone else from being there. I really think that a large number of leaf-node employees are massively under-employed compared to what they are capable of. I guess it's kind of a reverse-impostor syndrome.
I think it sounds like they were remarkably accommodating. I doubt you'd find many companies these days that would grant the same sort of deal.
