As far as knowing about the workings of a company, I'd definitely bet on the college student. The observation in my other comment applies to general adults as well.
Ok I'll stop taking the joke too seriously now :P .
College students have spent much longer being indoctrinated that corporations are good, and the bigger the better, than have five-year-olds. In that sense the joke actually was -- at least to some small part -- serious.
Mate, 80% of college students don't know that.
