An inside look at the secretive world of elite philanthropists - and how they're quietly wielding ever more power to shape American life in ways both good and bad.

While media attention focuses on famous philanthropists such as Bill Gates and Charles Koch, thousands of donors are at work below the radar promoting a wide range of causes. David Callahan charts the rise of these new power players and the ways they are converting the fortunes of a second Gilded Age into influence. He shows how this elite works behind the scenes on education, the environment, science, LGBT rights, and many other issues - with deep impact on government policy. Above all, he shows that the influence of the Givers is only beginning, as new waves of billionaires like Mark Zuckerberg turn to philanthropy. Based on extensive research and interviews with countless donors and policy experts, this is not a brief for or against the Givers but a fascinating investigation of a power shift in American society that has implications for us all.
