Top management at the world's corporations need someone to take the blame when their decisions don't work out. So, what do they do? They hire a analyst or consultant from a consulting firm or financial institution for x hundreds of dollars per hour. But they can't just hire anybody, they need the "best" available. Otherwise their judgement could be questions if they hired some nobody. The consultant or analyst really don't do anything that any business undergrad could do or that the execs themselves could do, just some basic presentations and charts. They are essentially business whipping boys (and girls). Brand is very important for these types of jobs as you can imagine.
