It's called the bozo explosion. Insecure and less talented leaders usually want people below them ****** less secure and competent than themselves, because they fear being replaced. When you have a B, C, or D player, they only want less capable people below them. They chase away the more talented people away becaue they fear them. B players only promote and empower C players, who promote D players and so on. Talented and secure people, the "A players" want people below them to be just as talented,
