"The U.S. wants economic growth at any and all costs," said Axel Merk, president of Merk Mutual Funds, a Palo Alto, Calif.-based money manager specializing in currency investments.

　　That's a stance that many economists are growing increasingly worried about -- especially when you consider that the United States has about a $13 trillion debt load and is projected to have a record-high $1.56 trillion budget deficit in fiscal 2011.

　　This may be a bone of contention at the upcoming summit of so-called G-20 nations in Toronto this weekend.

　　"There has to at least be a plan for the U.S. being fiscally sustainable. It's amazing that we're lecturing Europeans on how to run their economy," said Thomas Cooley, a professor of economics with NYU's Stern School of Business. "Europe is at least addressing its problems even though there is pain associated with that."

　　There are several reasons to be worried about current U.S. fiscal and monetary policy. Merk said that his biggest fear is that the United States is boxing itself in a corner and feeding potential inflation by issuing lots of Treasury debt and keeping interest rates low.
