Alfie Kohn is against all forms of compitition. I don't think he ever referenced economics, but he said even competitive sports are bad. Kohn even has a book about how bad compitition is. No Contest: The Case Against Compitition. Honestly he is not my favorite when it comes to Voluntaryist lifestyle recources. A lot of his stuff is really good but there are things mixed in there that turn people off, like his rhetoric and this kind of stuff about compitition. I mean compitition is one the greatest incentives as proven through the free market. It's hard to buy into his arguments when compition in the market place is so well proven.
