I do think that the royal family is a good thing, because it gives their subjects something to be proud of, without actually affecting the political system. I believe that the royal family is an important source of pride and inspiration. The world's continued fascination with them, despite the fact that they no longer hold any political influence, is a good example of their importance as figureheads.
The royal family is a family to look up to, and many people actually care about them. I think it is a beautiful tradition and one of the most precious symbols there is for many countries in the word. So many countries are united thanks to them, and they are definitely proud of such a symbolic union.
