YADNBU, I can't stand the monarchy and think all their assets Inc money, property, etc, should be surrendered to the state and, bar the Queen, Phillip and Prince Charles (only due to age), the rest of them should all have to start working for a living and pay their own way.
All the money from the Crown estate, etc, should be used to fund essential services such as NHS, cheaper public transport, etc.
If you go back far enough their riches stem from taxing ordinary people and landgrabbing, etc, anyway so I don't see it as 'their money/properties' and I do think it should be restored back to the public.
Tourists would still come because the Palaces, etc, would still be there, same as people still visit Versailles, etc, so that's not a valid excuse. It's not like they get to meet the Queen when they're looking around Buckingham Palace.
