Gandhi famously said "Earth provides enough to satisfy every man's need, but not every man's greed." From an ethical point of view, it is extremely difficult to justify excessive wealth and inequality. In fact, most philosophers and all of the major religions caution against the pursuit of excessive wealth at all cost and prescribe sharing of income with less fortunate members of the community. For instance, the Koran bans usury and says that the rich should give away a portion of their money. The decision of Bill Gates and Warren Buffet to give away their fortunes or to call for greater taxation of excess wealth is an example to the rest of the world's billionaires.Is there a moral justification for excessive wealth and inequality?
Are billionaires, like Bill Gates, Warren Buffet, and other rich and famous people (see YouTube video), doing enough to alleviate the suffering of poor people or should they do more?
