In my current organization where I work, there is some ego driven power theories. If a person becomes well versed in his field of work, he starts to think what he wants to and also assumes that each of the steps he takes is right and perfect. I see this behavior clearly in my managing director of the company who seems to be really egoistic and thinks what he does is best for the company. He is having 25 plus years of experience in this field of work and is extremely accomplished and well versed in his work.
