But just because the numbers are small doesn't mean society does not support them. There just isn't a need for a lot of them. It would be like saying society does not support professional athletes. Clearly it does, but only at the highest level. And at that level, it supports the very well.

I apologize. I come from this world, have close friends in major orchestras and experience on the world's opera stages. This culture is full of shibboleths: referring to works as "songs", clapping in the wrong place, hell, even pronouncing 'Don Giovanni' the same way you pronounce "Don Draper" lets people know you are not from around here.
