摘要：Many have argued that the clear answer to the
title question is negative. The US currenct
account deficit, around $600 billion a year and over
five percent of US gross domestic product (GDP), is
without precedent in size, and indeed is so large that
it dominates the world economy. Although it is not
actually the case, every other country in the world
could be experiencing a current account surplus, and
many in fact are running surpluses.1
