Come on, dude. You can't expect them to stay poor forever.

They made good music and got rich out of it.

& Now their situation is the situation of every successful artist.

They become the prisoners of their own success,

Bound to remain in the persona until it doesn't work.

Think of Eminem for example. He is 55 and he comes on stage acting like he's still 25 because that's what people came to see. No one is really interested in the real 55-year-old Eminem. Everyone is here for the 'persona'
