For every one that makes it there are prolly hundreds that are just as talented that will consider themselves lucky to get tenure at a half-decent (state) university. There are undoubtedly many really phenomenal musicians out there that we will never even hear of. I truly believe that.

Once talent is at a professionally proficient level it's all about who you know. Generally speaking, one with "merely sufficient" talent who has great teachers and contacts will get further than one with extraordinary talent without such conctacts. It's only what you know to an extent: beyond that it's who you know.

Despite our love, understanding, and passion for classical music, the majority of the world really isn't too interested and doesn't support it and there just isn't room for many: a few lucky ones win the lottery with a ticket their contacts buy them.
