I think what people don't understand about the monarchy and the royal family is that they are not 'superior' to us, they are performing a symbolic role for us.
The Crown is symbolic of the nations history and unity.
The monarch is symbolic of the crown.
They are not chosen for their superiority they are just given this role by birth. That means we will over time get some monarchs who rise to the significance of the role, some who cannot and some who reject the role. That will be the story.
The alternative is a popularity contest where we periodically decide who has convinced us they'd be great at the role.
I think that way we'd get some great representatives and some terrible ones but in a different way to now. They'd all be people seeking it for themselves.
So Harry's harping is ridiculous. No one thinks the monarch is a superior person, or more worthy, they are just the person given the symbolic role. Which only one person can do. William is that person.
If we were a republic I'm sure him and meg would run for president of the UK. They believe they have the qualities.
In fact HMQ was a very ordinary women who would never have sought the role but who commited to it in an extraordinary way because she believed the symbolism of it was deeply important.
