An examination of how today’s leading philanthropists are revolutionizing the field, using new methods to have a vastly greater impact on the world. For philanthropists of the past, charity was often a matter of simply giving money away. For the philanthrocapitalists – the new generation of billionaires who are reshaping the way they give – it’s like business. Largely trained in the corporate world, these “social investors” are using big-business-style strategies and expecting results and accountability to match. Bill Gates, the world's richest man, is leading the way: he has promised his entire fortune to finding a cure for the diseases that kill millions of children in the poorest countries in the world.

考察当今主要慈善家如何在这一领域进行革命，使用新的方法对世界产生更大的影响。对于过去的慈善家来说，慈善事业往往只是简单地捐钱。对费城的资本主义者来说，这就像生意一样，他们是新一代的亿万富翁，正在重塑他们的奉献方式。这些“社会投资者”大多在企业界受过训练，他们正在使用大企业式的战略，并期望结果和责任相匹配。世界首富比尔·盖茨（Bill Gates）正在引领这条道路：他承诺用自己的全部财富来寻找治愈世界上最贫穷国家数百万儿童死亡疾病的方法。
