We might end up owing them. It’s estimated the royals bring in £2.5 billion a year. Whereas they cost around £500 million. This isn’t just from Tourism. It’s from huge estates that they own which have farms, businesses, tenants. Just one of the estates that the Prince of wales manages brings in about £500 million pounds a year. There are many other families with significant inherited wealth, you just dont hear about them as much. For example the duke of Westminster owns most of central London, not by royal decree but by birth. So whichever way you look at it, they are an incredibly wealthy family. I am not even a monarchist I just think it’s a bit simplistic to say yeah fuck them! Take it all back. After a thousand years,It’s pretty difficult to untangle where the crown stops and the family begins.
