Yawn. The current accout plus the capital account MUST equal zero. Thus a current account deficit may mean foreigners don't like our goods as much as we like theirs OR it might mean that foreigners like US assets better than they like their own.
For example if Mark Steyn is right on the futre of increasingly Islamic Europe, then we will observe a US current account deficit for a century as Europeans sell their assets and buy assets around the world, particularly in the world's safe haven the US.
No Yawning. What you said is also true of other countries and those with a large CA deficit have had and ugly end. The US is different, but not so different that we get off pain free.
