The U.S. dollar has been crashing in world markets for several years.
The reason is pretty simple: The U.S. government and its import hungry citizens both spend way more than they make. To pay for this imbalance, the U.S. Federal Reserve just prints more dollars. Economics 101: When a commodity is plentiful (in this case, U.S. dollars), its value goes down.
That's why the Euro and the British Pound and every major currency have had double digit and even triple digit gains vs. the dollar.
But, alas, we keep printing more dollars.
So, we send those dollars off to far away places like China and Saudi Arabia. For our citizens,the conduits for this dollar transfer are, among other places, our local Wal-Mart (where we buy the goods from China) and our local ExxonMobil gasoline station (where we fill up our tanks with foreign oil). (For our federal government, a large conduit is Haliburton and defense contractors to finance George Bush's war in Iraq.)
China and Saudi Arabia are kind enough to send these dollars back. They buy our stocks, our real estate, and our Treasury notes. (The Treasury notes part keeps the cycle going).
But, notice something important. China and Saudi Arabia (and a host of other nations) are buying our means of production. In Michael Moore's documentary "Fahrenheit 911", Moore points out that Saudi Arabia actually owns 6% of the total stocks of companies listed on the New York Stock Exchange.
When you transfer your means of production (i.e. others are buying your stocks), you are transferring real wealth out of the country.
But, here's another interesting point: As the economy slipped into recession, George Bush decided to stave off the inevitable by writing checks from the U.S. government to all its taxpayers.
One problem: The U.S. government doesn't have any money. In fact, it's $10 trillion in debt. (FYI, Reagan, Bush 1 and Bush 2 are responsible for about $8 trillion of that. So much for "fiscal conservatism".)
So, the U.S. government, in essence, wrote bad checks to everyone, and, then printed the money to cover the bad checks.
Now, we can all go to our local WalMart and our local ExxonMobil station. China and Saudi Arabia can't wait.
