In the Sunday NYTIMES, Greg Mankiw rightly questions the widely held belief that the US is in some sort of a zero-sum economic competiton with emerging markets.
A far more articulate piece, that tears apart dubious claims made regarding the existence of zero-sum economic competition amongst nations, was written more than 16 years ago in Foreign Affairs by Paul Krugman (yes, the same Paul Krugman who now sounds more like an economically illiterate journalist; Krugman's evolution over the past 20 years makes one wonder if age really brings wisdom).
On a side note, those familiar with Krugman's China-bashing articles in recent months may find the following articles from the 1990s far more illuminating:
"In Praise of Cheap Labor: Bad jobs at bad wages are better than no jobs at all" by Paul Krugman
"The East Is in the Red: A balanced view of China's trade" by Paul Krugman
