Take a moment and go read about Richard Rainwater, one of Bush's multi-billionaire "personal friends".
He's made his money investing well during crisis. He sees another big money-making opportunity coming along, and he's put much of his fortune behind that bet ... except of course the $500 million in cash he's keeping around just in case things go to hell quickly.
Why is he telling us about it? Because this particular investment opportunity could also threaten the existence of mankind, and thus feels a civic responsibility to say something.
