Mr. Parkinson: I am disappointed in you and the Globe for such a one-sided exposition of this issue. Yes, comparative advantage is a powerful thought concept in Economics. That isn't a worthy story unto itself. Are you aware of the field of "behavioral economics"? It was created from the tireless work of psychologist who realized that the predictive value of Economics works only in text books, and the human condition plays a significant role in the decisions and efficacy of economic policy. You may find it useful to investigate why comparative advantage is not fulfilling its promises in our global economy. Do you honestly believe that China will always want to be the cheap labor manufacturer for the west? How much do you know about the tech innovation industry in the Pearl River Delta? One country's comparative advantage of yesteryear is not a fait accompli for the remainder of time. I hope you would agree that it is actually possible to do more contemplative and insightful journalism.
