When you become extremely rich, you become isolated. You will be surrounded by people, but they will not be equals or peers who will talk frankly and honestly with you. They will only be there because of the money and if the money vanishes, so will they. You will be, essentially, alone with your staff and the constant buzz of people attempting to get something from you. You will trust no-one, feel no loyalty, and avoid facing what you have lost. On paper billionaires are rich, but in practice they are some of the poorest people alive.
