There are anywhere between 150-204 billionaires WORLDWIDE who have signed THE GIVING PLEDGE which was created by billionaires Bill&Melinda Gate/Warren Buffet. The pledge states they will give at least half their wealth to charities. In some cases some have pledged much more than half. It is estimated that pledge may be worth about $600 BILLION by 2022.
So all billionaires aren't the selfish greedy seedy needy money-hungry hoors you see front and center in politics.
