"In fiscal year 2001, Nike and the Nike Foundation contributed nearly $29 million in cash, Foundation grants and product to various charities, nonprofit organizations and community business partners around the world. US Nike employees donated approximately $1.8 million to charitable organizations. Nike's corporate commitment to employee involvement matched those contributions dollar-for-dollar. Nike matched 41,376 hours of employee volunteer time, for a community investment of $413,760. More than 1,346 different charitable organizations benefited from the generosity of Nike employees."

I found those links in a Google search which took 5 seconds, BTW.
Have you thought this concept of specific altruistic obligations amoung "rich fat bastards" all the way? Like what defines "rich fat bastard" (is it having a net worth of $1,000? $10,000? $15,000? A million?) Or why this obligation somehow doesn't apply to you, despite it applying to everyone who neatly fits into your concept of rich people?
