Comparing head coaches to corporate executives is about the worst analogy I can think of.
For one thing, out of 1 million things, you’re going to compensate your employees and it is basically in writing and the minute you deviate from that they can and you take you to court. Secondly corporations don’t have to be the only winner as in football. They can have growth and be successful and be far from the number one competitor in that market or product or service. If the shareholders are making profit and the employees are gainfully employed then there’s very little pressure to lie or cheat.
