One Hundred Thousand Dollars a year in Royalties from iTunes seems pretty low. I'd be curious to see how much iTunes made off them vs. what they paid them in royalties.
Additionally, consider the fact that any royalties earned and any proceeds from live shows go into a collective pot that is the Eagles Corporation -- whatever the name may be. From that, deduct: The cost to lease or rent the venue, musician's salaries, roadies salary (and propably their medical insurance which is astronomical) security staff, lighting and sound guys, production people, Irving's cut, TAXES, behind the scenes support staff, travel expenses for everyone, liability insurance, etc. . . The costs go on and on and they are staggering.
It's not like Glenn is stuffing half a million dollars in his guitar case and running out the stage door with an evil grin on his face.
Then consider the additional individual expenses of the Principle band members after they are paid -- or their respective Corporations: Attorney fees, accountants, insurance costs, personal and corporate employee salaries and benefits, taxes and all other expenses incurred by a successful business -- not to mention wives, children, parental support, charitable contributions/foundations, etc . . .
As far as ticket prices go, they're a reflection of what people are willing to pay. If they charge $230. and nobody is buying, they'd have to adjust prices accordingly. That doesn't seem to be the case. They consistently sell out every venue they play.
Will they be in the poor house any time soon? Doubtful. They have worked long and hard for their success and I for one don't begrudge them a dime. JMHO.
