Billionaires are responsible of more deaths than the numbers they are. If we accept those death in the name of law and democracy, maybe we should try for once eradicating the root cause. They should be able to choose to give their money back or die.
There are many ways in which every billionaire is a policy failure, but the most corrosive and destructive way in which billionaires are policy failures is this: billionaires, despite being unelected and unaccountable, possess the power to control - and ruin - millions of peoples' lives.
