The thing is... there is not another family like it. Probably not in the world, maybe vague similarities with other European royal houses, but none of them like this. They have far far more money spent on them than not far off all the others put together. See attached.
My take on it is...
Successive governments refuse to discuss anything to do with the Monarchy for fear of vote losing. It's a hot potato.
The royal family are unique, nothing like other rich families, they are bound by rules and protocol and so make up for it with the sort of behaviours we witness. Because they think they deserve it. They are, in essence, a dysfunctional hugely rich family, no more no less. The RF could do what they liked before the advent of mobiles, social media etc. Now those days are gone with QE2.
Charles had a chance to change the Monarchy drastically for the better. He chose not to.
And it will only get worse when he dies.
