What should billionaires do with their money? The world’s greatest philanthropist, Andrew Carnegie said they should give it all away. Andrew Carnegie was born in Scotland and moved to America where he became a steel magnate and the richest man in the world. In his guidebook to philanthropy, The Gospel of Wealth, he challenged people who acquired great wealth to give it back to the community. He also believed the most important cause to support was education. Former UK Prime Minister Gordon Brown asks why today’s billionaire philanthropists aren’t giving away more money and why education is no longer the top priority.
