For full disclosure, I am prejudice as I like the idea of the UK being ruled by benevolent, mythical monarchs.
As an American I can enjoy the exploits of the royals without having to pay taxes to feed them. USA, USA!
For the slightly random trivia.. As from someone here in deepest, darkest depths of southern England.. The Monarchy as such don't just get the money for nothing. It's from awhile back, but the Royals basically cut a deal with the UK government here.. they "gave" huge chunks of real estate that they owned in person to the Government, in return, they get a continuing amount of money each year.
Note - the amount of money is
significantly less then what they'd get actually leasing the land or using it themselves. And if I remember correctly, if the Government wants to stop paying the Monarchy, they can just give the land all back.
