This is what most of our celebrities do. These are people who have lots more money than average. Instead of dealing with their own guilt issues, they go out in public and proclaim that "we should all give and give until we can give no more." Think about the source here. With the typical celebrity, you're talking about someone who has way more money than most of us will ever have. And these are the people who are telling us how to spend ours--whether it's through private charity or, as in many cases with heavy-handed liberal celebrities, much more taxation and restriction of our own expenses.

My advice to really rich people who want to help others: Do so. Use your own judgment. And shut up about it.
