Management is about extracting value, which is what most of those on replies on StackExchange are doing.

Leadership is about training new leaders.

Bob is a kick-ass employee. Why not make him into a leader and have him figure out ways to make the other employees just as productive? He has to learn to multiply his effort. He doesn't need to be a manager to do that; he just needs to be made into a stronger leader and be given progressively larger scope.

Leadership is a worthwhile activity for sure, but if “Bob” doesn’t get enjoyment/satisfaction out of it, then it could be perceived by him as more of a punishment.
