You only need to look at the way they're covered by the media. I'm young enough that this is the first generation where I've seen people become royal overnight, and the way the media turned on a dime with their reporting was incredible. They used to report on Kate Middleton roughly like they would any other celebrity. Maybe a bit more respectful, but generally similar. Then when they got married, "Catherine, the Dutchess of Cambridge" was suddenly spoken about in hushed, reverent tones, as if we should somehow admire her. Certainly on the BBC, the way they report on the royal family is massively different to anyone else.
