     Raymond Schneider politely made his way through crowds of customers as he made for the candy

bins at Dylan's Candy Bar in Manhattan. Since he was out of employment, Mr. Schneider, a

33-year-old designer, says he has become a person who always buys a lot of sweets every time he

shops for groceries.

"Sugar is comforting," he said. "There's nothing more stressful than growing financial insecurity (不安

全感) everywhere."

     The recession (经济衰退) seems to have a sweet tooth. As unemployment has risen, Americans,

particularly adults, have been consuming (消费) growing amounts of candy.

     Theories vary on exactly why. For many, sugar lifts spirits dragged low by the economy. For others,

candy also reminds them of better times. And not importantly, it is relatively cheap.

     At Candyality, a store in Chicago, business has jumped by nearly 80 percent and the owner, Terese

McDonald, said she was struggling to keep up with the demand for Bit-O-Honeys, and Sour Balls.

Many big candy makers are also reporting rising sales and big profits (利润).

     "It's not surprising." said Peter Liebhold, chairman of the Smithsonian Institution's work and industry

division. "During the Great Depression in the 1930's, candy companies stayed in business."
