We're Number...Four.

In just two years, the US has slipped from the World Economic Forum's most competitive economy to fourth this year.

The U.S. has slipped down the ranks of competitive economies, falling behind Sweden and Singapore due to huge deficits and pessimism about government, a global economic group said Thursday.

Switzerland retained the top spot for the second year in the annual ranking by the Geneva-based World Economic Forum. It combines economic data and a survey of more than 13,500 business executives.

Sweden moved up to second place while Singapore stayed at No. 3. The United States was in second place last year after falling from No. 1 in 2008.

The WEF praised the United States for its innovative companies, excellent universities and flexible labor market. But it also cited huge deficits, rising government debt and declining public faith in politicians and corporate ethics.

"There has been a weakening of the United States' public and private institutions, as well as lingering concerns about the state of its financial markets," the group said.

Mapping a clear strategy for exiting the huge U.S. stimulus "will be an important step in reinforcing the country's competitiveness," it said.

Of course being able to get out of the need for stimulus is more important, and that's not going to happen anytime soon.  So yes, 13,500 business executives are a little sore at the US right now.  Go figure.
