The Taylor Swift example rather shows that there are more (somewhat) young people that can afford high ticket prices these days.
Also: I was extremely conservative with the inflation adjustment. You could probably equally well argue that $8 in 1970 is more like $60 today, as the basket to calculate inflation changed very unequally and services generally inflated much more than goods.


















That completely ignores my argument.
Rock and Roll music was not something well off elderly people went to concerts in the 1970ties.
