We need economic policies in the U.S. that produce jobs, first of all, but good jobs, second of all. Believe it or not, Germany, a country characterized by high wages, strong unions, a social safety net, and so forth is the second largest exporter (after China) in the world. The idea that the only way to succeed is by eliminating vacations, sick days, worker protections, and so forth is simply belied by the competitiveness rankings produced by the Economist magazine's intelligence unit and by the World Economic Forum.

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.

Trust is about keeping commitments, but in many instances, circumstances change and organizations therefore shed commitments, things such as retiree medical benefits, pension obligations, and even employees without much remorse or maybe even hesitation.

I don't think eliminating the knowing-doing gap depends on the amount of knowledge around. It depends much more on people's attitudes and intentions - do they actually want to turn knowledge into action, or just go through the motions of acting as if they are busy or are accomplishing something.

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.

I do not think anyone who ever saw Lyndon Johnson give a speech would call him charismatic, even though he was one of the most effective presidents in U.S. history. Same with Lincoln. Charisma is only one source of power, and probably not a very important one, at that.

The single biggest barrier to effective leadership is, in my view, the leadership industry itself. Instead of telling people the skills and behaviors they need to be effective in getting things done, we tell them almost the opposite - blandishments about how we wish people would be, and how we wish workplaces were. That information is worse than useless as, to the extent people believe it, they often wind up losing their jobs.
