Peter Thiel, PayPal Co-founder
Peter Thiel is an internet entrepreneur and a libertarian. He wants to encourage free thinking and he thinks his business ventures demonstrate big ideas -- PayPal, which he co-founded, created a way to make payments online. Facebook, which he took a big stake in, connected people around the world. Now he tells Mike Williams that his venture capital fund and philanthropy are aimed at encouraging the kind of technological innovation that the West needs to survive.
