Harry walks a difficult tightrope here because on one hand he can't be killed but on the other hand he can't be elitest or people will hate him. Although, he is sort of the British aristocrat version of an early, irony free Tori Spelling in the sense that it doesn't matter what he does, he's never going to be the actual King and will always just be the second kid born.
He's done everything right in the media with reference to making it clear that he doesn't want to be treated differently to anyone else - although, that's more or less impossible when you get right down to it.
It could easily help his image if he also released a series of black and white nude photographic portraits as well. Easily.
