I think Rose makes fascinating points. And I would like to add that one, if not the sole, reason for the Royal Family being in such a precarious position is that their wealth and power is ultimately derived from the fact they are the remote descendents of someone who did something nearly 1000 years ago.
Aside from other monarchies (and there are only another seven that can be described as being this old), what other elite family in the world owes their position to events that occurred practically a millennium ago?
It's a bit like Jeff Bezos being Jeff Bezos because he is a descendent of one of the pilgrim fathers.
It's utterly bonkers when you think about it. Most modern global elite wealth and power comes from the fact someone has done something within the last fifty to one hundred years, and respect tends to coalesce around those individuals and families that are perceived to have created a good for global society (Bill Gates in creating Microsoft, for example). Respect and fond feelings do not just appear because one "is" wealthy and powerful; they have to be earnt.
And the Royal Family has realised, albeit belatedly, that being perceived as "doing good for society" is the only tool it has in its box to ensure its survival, which is already in a precarious state by virtue of its reliance on public and political will. And that "doing good" had to be the real deal; it has to be the modern version of the vicar's daughter going round to take provisions to the sick and impoverished. Diana understood this implicitly; there had to be an element of doing good on the ground in situations that others would shirk because it wasn't glamorous or pleasant.
But Harry seems not to have fully understood this. Neither has Meghan. They don't seem to understand they get the coverage they do because the entire royal family has been living on borrowed time since the 17th century, and the only thing that keeps their heads above water today is a willingness to do boring, miserable, sad, and tedious duties like opening leisure centres and attending ceremonies.
