We need to reexamine and reassess the purpose of the corporation, and go back to the idea that senior leadership has responsibilities not just to shareholders but also to customers and employees.

Business school graduates from the best schools earn large salaries and frequently rise to positions of great power. It would be nice if they used that power to truly make the world a better place - which entails more than just maximizing their own organization's profits and their own economic well-being.

We need to reexamine and reassess the purpose of the corporation, and go back to the idea that senior leadership has responsibilities not just to shareholders but also to customers and employees.

Those who have power a) understand that the world is not always a just and fair place and accept that fact, b) understand the bases and strategies for acquiring power, and c) take actions consistent with their knowledge in a skillful way. Skill at anything requires practice, and power skills are no different.

To paraphrase the late management thinker and writer, Peter Drucker, thinking is hard work, which is why so few people (including actually senior managers) do it. Once there is some "conventional," seemingly-reasonable story, people just accept it and don't ask, "is this actually true? Is it consistent with the data?" And this extends to the highest reaches of organizational life.

People clearly want to believe that the world is a just and fair place. It provides them a sense of control and makes them psychologically comfortable. But believing that the world is a just and fair place causes people to not do enough to take care of themselves and to be unprepared for when it isn't so nice. So, people need to understand their tendencies to see the world as just and fair and then be realistic about the actual conditions in which they find themselves.

People tell me the Netflix series, House of Cards, is sort of like my class come to life. The movie Margin Call portrays the realities of hierarchical relationships and rivalries beautifully, and how people respond when under pressure. Gandhi and Long Walk to Freedom both have the virtue of presenting larger-than-life figures in a more realistic way, showing their flaws and contradictions - their humanity - in a way that is very helpful.
