This is the monarchy we are talking about, putting a limit on their spending would be futile, who would enforce it (monarchists), who would investigate any wrong doing (monarchists). Too many vested interests , nice idea though.
The heirs receive nothing unless they are standing in for the Queen and doing official duties but, as there is Noddy's friend and his old slapper, Prince William and wife, Prince Harry and,,,and,,,,and whoever he has on hand and Princess Anne the rest of them have to fend for themselves, no state hand outs.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
