Viliam, good point about the general principle of a million bucks, although it would probably be more in the modern world.

However - and this is something I chose not to go into in the article due to word constrictions - people who go into medicine don't have that mentality. They generally have a mentality of working as a doctor throughout their life until they retire. It's really hard to choose a Schelling point to stop working in that sort of profession - doctor, lawyer, etc. It's much easier for entrepreneurs who have a natural out when their business gets bought out. Doctors etc. often association their source of meaning and purpose with their professional activities.
