I'm surprised that there is so much controversy about this article - nothing Paul Krugman has written here is outside the mainstream in international economics, in fact it can be taken out of a textbook (in fact the author has written a very popular one on the subject). The point or the article is simple - you are going to have a new set of problems to work out, please think about them, don't assume the best possible outcome. I didn't see a radical policy proposal that could possibly offend anyone. A lot of people seem to dislike the examples - but this is just nitpicking to show off.
