There is nothing much happy than give away the things for the needy. This feeling made popular US billionaires to pursue forty US billionaires pledged to give away at least half of their wealth to philanthropic purpose in response to a campaign by Microsoft chief Bill Gates and legendary investor Warren Buffet.
Among those who pledged their contributions are New York mayor Michael Bloomberg, noted Hollywood director George Lucas and media mogul Ted Turner.
The US has 403 billionaires in the world - the most in the world, and New York tops the list within the country.
Buffet, who heads the insurance and investment company Berkshire Hathaway Inc, has pledged 99 per cent of his wealth.
"In 2006, I made a commitment to gradually give all of my Berkshire Hathaway stock to philanthropic foundations. I couldn't be happier with that decision," he wrote in a pledge letter.
"Now, Bill and Melinda Gates and I are asking hundreds of rich Americans to pledge at least 50 per cent of their wealth to charity."
In his pledge, Bloomberg underlined the need for rich people to give away their wealth now and not wait until they were dead.
"The reality of great wealth is that you can't spend it and you can't take it with you," he said.
"And so I am enthusiastically taking the Giving Pledge, and nearly all of my net worth will be given away in the years ahead or left to my foundation."
The campaign does not require billionaires to make donations to The Giving Pledge, but only to give away their wealth in some charitable cause of their own choice.
George Lucas, creator of Star Wars and Indiana Jones movies, highlighted the need for reforming the education system in the US, to something more than "an assembly line with producing diplomas as its only goal."
"When I was in high school, I felt like I was in a vacuum, biding time. I was curious, but bored. It was not an atmosphere conducive to learning," Lucas wrote, noting that he started 'Edutopia and the George Lucas Educational Foundation' to push educational innovation.
