I know a lady who was long ago an opera singer who had the same complaints about productions she used to attend in the recent past. She got a call from a company to renew her subscription. She pointed out exactly what you said. The caller agreed but said they weren’t being made for her older generation and then asked if not a subscription maybe a donation. She said to go fornicate themselves.
The joke is that younger people aren't attending either - they're into hip-hop or other crappy pop culture. "Older" people who can afford tickets and are into the music are still primarily the ones who go to the opera.
