Can you elaborate on your rationale? I ask because I've worked in hospitals run by a cadre of physicians and it was not run well. Anecdotal, obviously, so I'm curious on your thoughts on what they provide.

My worry is that it can lead to an unbalanced technocracy. It's like saying a politician needs to come from [industry x] to govern [industry x]. Technical competence is a necessary, but insufficient criteria when managing a multifaceted problem. The risk is that the front-line physician priorities would always become the organization's top priority. In reality, a hospital administrator has to manage competing priorities across many different domains.
