<p>The motive here should not be money because both schools would place you well above the average graduating college student financially and in job opportunities.</p>
<p>If you truly want a solid business program (not just tech business) to go along with your science/tech major, then go to CMU.
MIT would probably be better for a mostly science/tech oriented career.
However if you are doing computer science, both schools are just about equal</p>
