When a cell doubles and redoubles, sequestering nutrients and resources, unchecked and uncontrolled, to the detriment of the surrounding tissue and eventually the entire body, we call it 'cancer'. When a person sequesters wealth and resources, land and corporations, drunk on power, unchecked and uncontrolled, to the detriment of others and eventually to society, we call them 'billionaires'. Greed is a disease.
