Are you bitter? A lot of American workers are, according to a new national survey.

In the Marlin Co.’s 14th annual “Attitudes in the American Workplace” poll, nearly 75 percent of workers said the American Dream was less attainable today than eight years ago. And 52 percent said it was unreachable for the average American.

The survey defines the American Dream as the opportunity to have a nice home, financial security and hope for the future.

Nearly half of the respondents said they are “bitter because the political system has caused a deterioration of (their) economic circumstances.”

“The Marlin workplace poll uncovered an attitude shift among U.S. workers who are more disillusioned and fed up than ever,” said Frank Kenna III, president of Marlin, which is a North Haven, Conn.-workplace-communications company.
