When a person's wealth exceeds any material needs they may have - a disconnect begins to form. They start drifting away from reality - what once worried them becomes unimportant, not just for them but for everyone, they simply stop seeing it. They become unreal and their only challenge is gaining more. And when they have it they need to find ways to spend it. Like building a $70,000 miniature playhouse for their dog. Being rich is longed for but rich people - evidence the news for the last 30 years - end up doing stupid things and literally losing their minds. Best to give it away early. Keep what you need, make other lives better with the rest.
