Whether a graduate's job could be done by a non-graduate ("Medics and artists top job league", August 13) is the wrong question to ask when thinking about how many people should go to university. The correct questions include whether a given person could do their job better if they were a graduate (or whether they do it better because they are a graduate); whether they gain in other ways from university; and whether the rest of society gains from interacting with this person as a graduate rather than as a non-graduate.
