At the moment, in Britain we're facing such enormous cutbacks in education programs and music programs and art programs that you feel you are knocking your head against a brick wall.
If you're writing a piece for the Boston Pops, the balance is towards one end. If you're writing a piece for a chamber music society, then it's towards another point. I won't make a final answer on that. I think it changes with every piece.
The present government is very insistent that business sponsorship should replace government sponsorship of the arts. Business sponsorship won't happen unless you make tax concessions, which they won't.
The establishment in Britain is certainly against the arts and against education. If something doesn't make a profit, it's invalid, and art doesn't make a profit in that sense.
