If that means that music is only created by those passionate enough to make it themselves as a hobby without any thought of remuneration ... well, that actually sounds like a pretty good filter to me. If you think that that means that music will die out, then that probably means that nobody cared enough about it in the first place. If you think that that will decrease the overall quality, I've been surprised at what dedicated volunteers can do, see open source.

Growing up as a kid, I was excluded from the culture of my peers as my parents (despite my pleeding) could not afford it. The plight of the starving movie director does not convince me.
