BOSTON ( TheStreet) -- Wall Street, the Federal Reserve and the Obama administration say the worst of the economic malaise is over, but U.S. entrepreneurs beg to differ, according to a survey by The Ewing Marion Kauffman Foundation, the largest entrepreneurship group in the world.

A total of 68% of more than 250 entrepreneurs and 150 would-be entrepreneurs said the economy hasn't begun to recover, and 59% believe conditions are getting worse. The poll, which included overlap in responses, was taken Sept. 8 to 12. (Entrepreneurs were defined as those who started a small business and are still running it, and would-be entrepreneurs are those who want to start a business but haven't yet.)

More than a third of the respondents said they've shed jobs in the past year, 5% have added employees, and over half said business volume and profits have decreased. Their findings come as the U.S. slogged through the longest recession since the 1930s, hobbled by financial and housing crises that have doubled the unemployment rate. Nevertheless, Fed Chairman Ben S. Bernanke has signaled the recession is all but over, and investors have sparked a stock-market rally.

Economic downturns historically have been good to one-time entrepreneurs, according to the Kauffman Foundation, which also reports that more than half of the companies on the 2009 Fortune 500 list were launched during a recession or bear market. During the bear market that lasted from 1973 to 1982, entrepreneurs Bill Gates and Paul Allen founded Microsoft ( MSFT), and Bernie Marcus and Arthur Blank founded Home Depot ( HD). One-time startups Micron Technology ( MU) and Amgen ( AMGN) were also founded during that period.
