He's "earned" it?
He hits a bloody tennis ball, for f***'s sake!
He's earned it because he has got there through a lot of work and sacrifice and talent alone. And because just a handful of privileged players can reach those heights. And because he's an icon that attracts sponsors. Would you rather that a crappy pop singer or actor makes that kind of fortune? Yeah, I think he has earned it. It's not like someone gave it to him or he inherited a fortune.
