There's an argument to be made about all the licensing he's done. But I doubt money is the overriding goal at this point. There's no reason in the world he would still be touring if he didn't enjoy it.
I don't begrudge him. I just wish music and writing were the only things he did. Maybe he'd have even more of a catalog and additional books. He's made a ton of cash, I'll give him that. He's had a great career by just about any standard.
