I think you're right. And you'll find that these people make good money, regardless of qualification, as long as (and only as long as) they make good momey for the studio. However, don't dismiss their short-lived mediocrity as a total lack of talent. You only have to watch "X-factor" (the initial auditions) to realise how many people are out there who lack even the most basic talent.... If an Arts degree has low income potential, that is no reflection on the value of the degree or the ability and effort required to attain it. They may be pearls; it is just that the world is full of swines.
