Philanthrocapitalism is based on the idea that capitalist models are the best way to create economic and social progress. Under philanthrocapitalism, charities are run as business models that employ market-based solutions to problems. The focus is on entrepreneurship, efficiency and quantified costs and benefits. Most philanthrocapitalist organizations are funded and run by the extremely wealthy. Some examples are Bill and Melinda Gates (Gates Foundation), Mark Zuckerberg and Priscilla Chan (Chan Zuckerberg Initiative) and Warren Buffet (The Giving Pledge).
