There was an article published in 1958 by the music academic and composer Milton Babbitt which was somewhat infamous in its day and raises a number of matters that have been the subject of recent discussion/debate/mudslinging here.
As performers, educators and/or members of a possible "elite" audience we all play a role in this just as much as actual composers.
I have attached the complete article below and encourage you to read in full, but for those with ADHD or a low boredom threshhold, here is the Cliffs Notes version (from Wikipedia):
Babbitt describes "serious", "advanced music" as "a commodity which has little, no, or negative commodity value", and the composer of such music as, "in essence, a 'vanity' composer". It is music of which the general public is largely unaware, and in which it takes no interest. "After all, the public does have its own music, its ubiquitous music: music to eat by, to read by, to dance by..." Performers, too, are seldom interested in "advanced" music, so that it is rarely performed at all and the exceptional occasions are mainly "poorly attended concerts before an audience consisting in the main of fellow 'professionals'. At best, the music would appear to be for, of, and by specialists". Babbitt goes on to maintain, however, that music cannot "evolve" if it only attempts to appeal to "the public". "And so, I dare suggest that the composer would do himself and his music an immediate and eventual service by total, resolute, and voluntary withdrawal from this public world to one of private performance and electronic media, with its very real possibility of complete elimination of the public and social aspects of musical composition." He recognizes the practical problems for the composer of "advanced" music not patronized by the concert-going public: "But how, it may be asked, will this serve to secure the means of survival for the composer and his music? One answer is that after all such a private life is what the university provides the scholar and the scientist." He concludes: "if this [advanced] music is not supported, the whistling repertory of the man in the street will be little affected... But music will cease to evolve, and, in that important sense, will cease to live."
Do you agree with Babbitt's argument?
EDIT - Corrected spellings of Babbitt. For the life of me, that last "t" seems just wrong!
