I became a fan of Professor Schwartz when a student of his sent me this video a few months ago. It is excellent. He just takes it right to Paul Krugman.
The clip in various forms has been seen over a million times. Not bad for an economic debate.
The below video is also excellent. Professor Schwartz discusses the nature of man, the economy, and the state. I wish I had taken a class with Sr. Schwartz. This is pretty close.
