With its violent crimes, high unemployment, dwindling population and financial crisis, Detroit was named by Forbes magazine on Thursday as the most miserable city in the United States. It toppled Miami, which held the title last year, and surpassed Flint, Mich.; Rockford, Ill.; Chicago and Modesto, Calif. in the top five. "Detroit's problems are hardly news. It has been in a four-decade decline paralleling the slide in the U.S. auto industry," writes Forbes.
