Berkshire Hathaway's Warren Buffett ranks No. 1, followed by Microsoft's Bill Gates, homebuilder Eli Broad, hedge fund trailblazer George Soros and media magnate John Kluge.
At the bottom of the index: Viacom's Sumner Redstone (47), Anne Cox Chambers of the Cox media empire (48), Microsoft's Steve Ballmer (49) and News Corp. founder Rupert Murdoch (50).
Lipman is quick to note that some big-time donors "aren't publicly giving," so the index has its limits as a barometer, but adds "executives who are successful should be out there talking about their giving."
Some of those who subscribe to that thinking have told her: "At a time like this, you need to step up and make an example."
