I seen this word and instantly thought that describes Toxic Peoples attitude to a T. I see them as empty shells that have a Huge Void within. They Truly Believe that Money, Power, Control, Materialism, Wealth will bring them Happiness. I say, its a temporary High they experience, then they are miserable again. The hunger for more becomes a vicious circle that Spirals downward only getting worse. The Character Trait noted in them is their EGO. Its all about them - Selfish & Self Centered.
