Some people feel philanthropy is only about foundations donating lots of money, but that’s only one part. Philanthropy is about people giving their time, help and care to causes they support, making the world a better place to live in. Philanthropic activities come in many forms, some people choose to contribute a huge sum of money to charity or create a park for the community. Some like to create facilities for recreation or provide scholarships for needy students. People love to hate rich people because they are often unaware of how the rich quite often use their fame and fortune for philanthropic purposes. The following is a list of 25 such outrageously rich people that understand the phrase “with great power comes great responsibility.” In no particular order:
