I remember reading a book, way back before 2000: "On The Psychology of Military Incompetence by Norman F. Dixon". It is about how people choose careers not based on what they bring to the table but what those positions do for them. It is about the authoritarian personality and how acquisition of power compensates for their fragile egos and fears.

The book covers the psychological factors that lead to leadership failures. It explains why those most driven to increase their status are often the least suitable for management positions.

Since societies are hierarchical we are continuously faced with the consequences of the wrong people in roles were they are taking decisions which affect millions. I found this book an interesting read.
