No less extraordinary perhaps than people waking up in palaces. Or belief that someone has a divine right to be head of church, army and state.  Or the private school system which can cost over £40,000 per child per year in a country where the average wage is £29,990.  PS. Wikipedia tells me there are 809 hereditary peers in the UK: 30 dukes, 34 marquesses, 191 earls, 111 viscounts and 443 barons.
