As for the word "litist", I wonder if it has become a substitute for "minority"? Am I litist or just a member of a minority if I enjoy reading 17th century English metaphysical poetry, which costs nothing in monetary terms? If price is what is involved, why not just say so, although the argument then changes. How many people this holiday weekend will spend large and small sums just enjoying themselves in a wide variety of ways that will be beyond criticism by your reporter.
If the problem is one of taxpayers' money subsidising the rich, then the argument should not be confined to opera but to all the performing arts. Within its grant Covent Garden is surely entitled to be flexible in its pricing policy: in my view it strikes a fair balance between the rich and the less well-off, among whom I include myself.
