I think a lot of it is that as we grow and age we tend to not see the same things we saw as a 20 something year old. I am not sure the music industry has changed so much, there were always, (pre virus days), sold out tickets to concerts.

Generation wise is there really any difference, every generation goes through their wars, shortages, and governmental screw ups, nothing has really changed other than we have aged and forgot to make the changes we dreamed of as we grew older.
