Wow. That sounds pretty negative for someone with such solid ties to the US and its government. I'd wager (perhaps foolishly) that the majority of your clients are probably US citizens as well.
But you're right, we're a pretty busy crowd. And, as far as philanthropy goes, we seem to be (privately) among, if not the most, generous people in the world. But I'm probably just looking through rose-colored glasses. I really don't think it would matter how much we gave away, it'd never be enough. See my previous post.
