You can't be a billionaire without pathology. The power, unlimited access to every resource, the inherent isolation, security implications, factual immunity to most consequences, morbidly twisted self-efficacy, the ethical dissonance of having it all while others starve... the human brain evolved adapted to scarcity and existential group boundaries to check on social pathology. These guys are holistically unchecked, inherently dysregulated on every axis. Their brain is constantly in an extraordinary, extreme state, trying to reach homeostasis for a life that couldn't be more distant, trying to find a model of reality which explains the abnormal signals it is getting.
