Justified in a capitalist system but not so much morally or for anyone with an ounce of reality.
Agree with the not going bit though as that's the only way it changes. And also appreciate that the cost of touring, using stadiums and so on will be rising for the artists themselves, but Adele's got 80k people over 20 nights if I'm not mistaken? Average ticket price £300 (conservative guess), that's half a billion comfortably. Greed... isn't she a working class hero...?
