I think the future goals largely play into the so-called "applicant pool" concept. It isn't only what background you are applying from but also where you want to go. The plausibility of your goals and explanations are I think more important than the area per se'.
Every admissions person I've talked to is cognizant of the fact that a reasonable % of people they admit find out IB/MBB isnt what they really want to do after they are admitted - sometimes even after one whole year of recruiting and interning in that function. So then the question arises: why so much emphasis on goals? People have been known to change right?
This is my perspective. There are, I believe, 2 reasons they stress the goals:
(a) Clear definition of where you are going and how you want to get there indicate a great deal of lucidity in your thought process. You like a person who is raring to go out of the gate and isn't going to spend the first semester learning about post-modern influences in art (unless your goal is to become a gallery owner/book publisher).
(b) In the event that you find out that what you originally thought you wanted isn't what you wanted - you are more committed to finding out what you truly want before your tenure at the school ends. You're the kind of person who worries OK consulting/Banking isn't what I REALLY want so what should I do - general management maybe? Then you bring the same lucidity of thought/enthusiasm you brought to your original goals to your new goal and you're still good to succeed.
Take for example someone who is looking start their own project after graduation - if the only criterion was placement statistics then nearly every person who applied with a goal of beginning their own company would hit the dust.
