Changing major senior year

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.

As well as the comments made here by Psata82, consider these by @juillet (http://talk.collegeconfidential.com/college-majors/1806472-majors-to-avoid.html#latest, etc):

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%.
