I would think so. MPP/MPA tend to be public sector. With an IR degree you have greater options of specializing in the private sector (international business for example.) This will definitely provide flexibility for your career outlook.
I am hoping to start at fifty thousand (no matter from which school I decide to attend.) I would like to try and get to six figures. Am I being unrealistic?
I also got accepted at Harvard and am having a difficult time justifying the sticker price. I think when it comes down to it, we must all remember that the main point of graduate school is to land us a good job, and that can happen from many universities.
