Throwing money at it doesn’t always work. The Facebook founder recently pledged $45 billion to charity over his lifetime. Sure, it’s a ton of money, but how he gives it away matters as much as who gets it. Which is why human rights consultant Michael Hobbes advises the 31-year-old philanthropist against launching big new projects, like his ill-fated $100 million venture to “flip” troubled schools in Newark. Zuckerberg’s money, Hobbes says, could have the greatest impact by supporting lower-tech networking, like organizing bulk vaccine purchases, for existing charitable efforts.
