Arnold Kling’s response to Holt, Havighurst, and Cohn is up at Cato Unbound. You know that I and Jon Cohn are going to largely find fault with Arnold Kling, while Clark Havighurst is a fellow traveler who actually says very sensible (but probably unrealistic) things about the tax treatment of health benefits.
In his response Kling agrees with my premises but doesn’t agree with my conclusions. Fancy that! Still go over there and read all the essays, because it’s good stuff!
