76 percent of American middle-class households not financially secure

As the economy continues to reel, a new report finds that 4 million American households lost economic security between 2000 and 2006 and that a majority of America's middle class households are either borderline or at high risk of falling out of the middle class altogether. The new report, "From Middle to Shaky Ground: The Economic Decline of America's Middle Class, 2000-2006," was published by the policy center Demos and the Institute for Assets and Social Policy at Brandeis University.
