The quest for money is the quest for power. This logic comes from people who have no interest in seeking a life worth living. They only seek a life where they have (illusory) control, because sometime, way back when, they were traumatized in a state of powerlessness. Now they only have the INSTINCT to prevent that from ever happening again.
