What is the "Giving Pledge"?

"The Illuminati supports the positive efforts of this planet’s elite and the initiative of the Giving Pledge. Originally conceived by Bill and Melinda Gates and Warren Buffett, the Giving Pledge encourages those with much to consider the needs of those with less."

"Bill and Melinda Gates and Buffett had drawn up the guest list. The late David Rockefeller served as host. They laid the groundwork that night for the Giving Pledge, an effort that, when it was announced a year later, was hailed as "the biggest fundraising drive in history." The Giving Pledge is a public, nonbinding promise made by rich people around the world to dedicate more than half of their wealth to charitable causes during their lifetimes or in their wills."
