You people are real simpletons.
Have a look at this:
US Assets are Falling in the Hands of Foreign Owners at Record Pace

As Warren Buffett, America's second richest billionaire, says, Americans are selling the farm to finance their spending.
That's essentially going to mean years of America having to export things to creditor nations without getting anything in return, beyond and above just what the trade deficits were.
Buffett even directed his own cartoon to try to warn people:
Some people will bring up the theory of Comparative Advantage, but the concept in that theory doesn't really apply when one country is trading away it's capital rather than products and services.
That turns out to be the primary "comparative advantage" of wealthier countries: their wealth. Trading it away.
I've never seen a textbook example of comparative advantage where one country's comparative advantage was it's land (as the most obvious example).
Obviously in these sort of scenarios, where capital is being traded away, that comparative advantage isn't sustainable in the long-term.
I also don't believe the economy of the U.S. is truly as fundamentally reliant on international trade as many people assume.
I mean, given 4 or 5 years it wouldn't be that big of a strain to convert back to local reliance. (with only the exception of a small number of specific commodities, like oil or coconuts for example)
