I think the first thing is to recognize a mistake that Obama made. And others have made in thinking that you can revolutionize a system that's unbelievably complex and interlinked, one-sixth of the economy. That was a mistake because whenever you change one thing, it changes 80 other things, and now if you're changing everything at once, you have no idea what the outcome is going to be and you get all of these unintended side effects.
