Warren Buffet
Warren Buffet is regarded as one of the most generous philanthropists in the world. Buffett started investing in the stock market at the age of 11. He still lives in a modest home in Omaha, Nebraska, which he bought for $31,500 in 1958. In fact, in one of his interviews, Buffet said that he never had any desire to have multiple houses and all kinds of things and multiple cars.
Buffet also doesn't seem to have much interest in spending on technology, particularly not when it comes to buying a phone. He uses a flip phone instead of a smartphone.
The 90-year-old has decided to give away nearly all his fortune to philanthropic causes by the time he dies.
He donated $2.9 billion worth of stock to nonprofit groups this year in July.
