Actually, yes, as it could open up career opportunities for others further down the totem pole. At almost every company I've ever worked, the CxO, SVP, VP roles were all hogged up by already-set-for-life people (or people who became set for life by working there a few years). They just hang on to those very senior roles like barnacles, while the rank and file fight each other their whole careers for a few open Director or manager roles.

If already-rich people could just admit they won the game and gracefully resign to "spend more time with their family" or "look down their noses" or whatever rich people like to do, maybe some of those Directors could be promoted to VPs and some of those managers could be promoted to Director and so on. This would help refresh the tree a little, cycle new blood through leadership, and help even more people climb the ladder.
