It looks like you are a full-time student, so probably have not probed the job market enough to have acquired enough information on which to make such a big decision as starting over with a new major.
On the Students Review dot com website (put /contact_center.php3?searchpid=41 after studentsreview.com), you can see the jobs many history majors went on to get. In their survey the job satisfaction of history and economics majors was the same (about 78%), history majors’ unemployment 5.6%, economics majors’ unemployment 4.4%.
