Founder of Amazon ($AMZN@US) Jeff Bezos said he plans to give away the bulk of his wealth in his lifetime, he said in an interview with CNN. Bezos has faced criticism for not signing the Giving Pledge, a promise by many of the world’s richest people to donate the majority of their wealth to charitable causes. In recent years Bezos has committed billions of dollars to charity with a $10 billion donation to Earth Fund and a $200 million gift to the Smithsonian National Air and Space Museum.
