That being said, getting 4 out of 5 economists to agree on something doesn't mean it's right. Most economists will tell you that public policy works best when you have the capability/political will to iterate on solutions. Not unlike a startup really.
When most economists see a debate between 'experts' on CNN (or Fox) I'm sure they're shaking their heads and sighing.
Imagine seeing a debate on TV about the merits of Java vs Windows - with the two experts being marketing people from Oracle and Microsoft. The whole thing would be a facepalm for HN readers - except that to an outsider, it would sound like a clash of brilliant minds.
