> A billionaire cannot just quit a job. There must be a transition period. A billionaire can't just no call no show.

Not only that, I imagine that quitting before retirement age could add a lot of anxiety for a billionaire due to loss of status, loss of purpose, feelings of failure, etc.

A billionaire has options though. They can often come back, or they can start a new company on a whim, but, as others have said, they often don’t “quit” but rather take extended time out that leaves them with the option of returning, when they choose to do so.
