Rock icon Iggy Pop is appalled by do-good rockers like Bono, because he is convinced they aim to profit from their humanitarian actions.

The LUST FOR LIFE singer insists that peers who seem to do nothing but fight for world peace and an end to hunger, should give up their day jobs if they're truly serious about their causes.

He tells men's magazine Penthouse, "It would be easier for me to believe someone's commitment to Greenpeace if that's all they do. I mean, work for Greenpeace if you believe in Greenpeace.

"Personally, I haven't done too many benefits but boy, when you do, you see the backside of it. I hear people talking about the angles and different things they're going to make off of it - especially the managers."
