Each country is 'different'.
The Prince and Princess of Monaco were very much loved and appreciated.
'All in all', sometimes it takes a King and Queen to more or less 'unify' a country. As long as they are good people who believe in civility, etc.
I don't know if any polls have been taken in the UK, but I have a feeling that most or many of the people there appreciate Kings and Queens, Prince and Princesses, etc.
I don't know how they might feel about all of the rest of royalty, but a good Prince and Princess might be a good thing in a country.
When I say these words, I think about JFK and Jackie Kennedy. Many people loved this couple, as I recall.
'More or less', 'Right or wrong', 'In general', and 'Just thinking out loud ' (as usual).
