I think it is partly because to get anywhere in the classical world, you have to at least proficient on your instrument. This is obviously not true in the world of pop music, where image and popularity rule.

I know classical gets lots of funding, but due to lottery funding, there is (going to be?) a music centre in Gateshead, with Folkworks being a major partner in it. And they are going to have a folk music degree course.
