From the article: "They were insular and struggled with intimacy, but they did believe in restraint, reticence and service."

Its been my experience that people who believe in service, which is to say they believe they are there to serve the organization/community/nation in order to help it achieve its goals, are the people who make great institutions.

People who believe in wealth acquisition and power make corrupt institutions.

The former live to empower everyone else, the latter live to dis-empower everyone else.
