There is no doubt that the monarchy brings stability. But stability isn't prized by everyone equally.
If you imagine one of those human pyramids popular with motorcycle riders and circus acrobats, those people at the top are very interested in stability. However, the ones at the bottom holding up the weight may not be so keen, and after a while start to wonder whether human beings were designed to behave in this way.
Stability is good for those in charge, less good for those who are kept in their place.
It's fine and dandy having one special family who are born to rule, but it means that other people must be born to be ruled.
I live in Liverpool where ambition is low and prospects are poor. Ordinary people do not think that they can "rise above their station" because this is just the way things are. There is no drive for improvement, for change, for a different life for the children. Schools are not fiercely aspirational for their children, because these children are never really going to get anywhere are they? With attitudes like this, it becomes a self-fulfilling prophecy.
These attitudes are found in the children, in their parents, in the teachers, in the system. They are derived from a society which values people for their parents and not for their talents.
The British Monarchy does offer stability. It is the keystone in the class system, holding it all together, and making sure that people know their place. In Britain, it doesn't matter how good you are, how clever you are, how kind you are or how resourceful you are, you will never be head of state, because that role is kept for those who have the right parentage.
It's great to have the pomp and circumstance, the ceremonial, the special people in the Royal Family who rule over us. But if some people are naturally superior, then others must be naturally inferior.
When we abolish the monarchy, the stability of the class system is not going to disappear overnight. But until we abolish the monarchy it will never disappear.
The sooner it goes, the better.
