I find royalty fascinating.
While I agree that the British Royalty isn’t what it used to be both from a power point of view and behaviour (the Queen herself is very much a lady) it is fascinating. Hopefully the younger generation will brush up its act.
No, they don’t live off taxpayers. Yes, taxpayers do pay towards them. The British are proud of their royalty.
As for your [rather idiotic] last sentence, the money is more likely to go to struggling football players.
