Ever hear of the Peter principle? It describes the often observed phenomena that people of some talent often rise to a position that they are emotionally or intellectually incapable of executing. It happens in business, sports, the military and politics all the time. Steve Bannon is a classic case. He is an intellegent, clever conservative who was given a high place of influence early in the Trump administration. He quickly came apart and was forced out. Lin Wood is another example. The air is a bit thin at the top and many caanot cope.
