When a country lives on borrowed time, borrowed money and borrowed energy, it is just begging the markets to discipline it in their own way at their own time.
...global markets are realizing that we [the USA] have two major vulnerabilities that this administration doesn't want to address: We are importing too much oil, so the dollar's strength is being sapped as oil prices continue to rise. And we are importing too much capital, because we are saving too little and spending too much, as both a society and a government.
"When people ask what we are doing about these twin vulnerabilities, they have a hard time coming up with an answer," noted Robert Hormats, the vice chairman of Goldman Sachs International. "There is no energy policy and no real effort to reduce our voracious demand of foreign capital. The U.S. pulled in 80 percent of total world savings last year [largely to finance our consumption]." That's a big reason why some "43 percent of all U.S. Treasury bills, notes and bonds are now held by foreigners," Mr. Hormats said.
And the foreign holders of all those bonds are listening to our debate. They are listening to a country that is refusing to raise taxes, and an administration talking about borrowing an additional $2 trillion so Americans can invest some of their Social Security money in stocks. If that happened, it would almost certainly weaken the dollar, further depreciating the U.S. Treasury bonds held by all those foreigners.
