The problem with setting your ticket prices too high is it stops young people joining your concert-attending fanbase, leading to your fanbase ageing

Totally a tangent, but I've noticed this with sports cars in recent years. The companies like to portray an image of glamorous professionals driving their cars and most times I see a Ferrari or a Porsche nowadays a more typical, older person is behind the wheel. I'm not judging if that's a good or bad thing, but I find it amusing versus the branding image. Could, too, all the fans at a highly priced Taylor Swift concert end up being 50+? :-)

Not all of them, but certainly a good amount.

Fans often age with the artist, and the same with cars somewhat.

Younger people (teenagers) will get to the concerts on their parent's dime, and many will go toward newer artists.
