"It tells you something about American culture that is unlike any other country," said Claire Gaudiani, a professor at NYU's Heyman Center for Philanthropy and author of "The Greater Good: How Philanthropy Drives the American Economy and Can Save Capitalism." Gaudiani said the willingness of Americans to give cuts across income levels, and their investments go to developing ideas, inventions and people to the benefit of the overall economy.
Gaudiani said Americans give twice as much as the next most charitable country, according to a November 2006 comparison done by the Charities Aid Foundation. In philanthropic giving as a percentage of gross domestic product, the U.S. ranked first at 1.7 percent. No. 2 Britain gave 0.73 percent, while France, with a 0.14 percent rate, trailed such countries as South Africa, Singapore, Turkey and Germany.
