More than 40 percent of recent U.S. college graduates are either underemployed or in need of more training to further their careers, a survey released Tuesday revealed. The online survey of 1,050 workers who finished school in the last two years and 1,010 who will graduate in 2013 found that many graduates, saddled with college debt, were in jobs that did not require a college degree. Thirty-four percent of students had loans of $30,000 or less, while 17 percent owed between $30,000 and $50,000, the survey found. While 53 percent of graduates found full-time jobs in their fields of study, many thought that studying a different major would have made them more successful in the job market. A third of recent graduates said they were making $25,000 or less, and 15 percent of this year's graduates thought they would earn even less once they had their degrees. The new survey's findings come soon after student debt in the U.S. hit $1 trillion, a new record, and surpassed Americans' credit card debt for the first time.
