I think I will say it having read all these replies. I would rather have Charles than most of you lot as HOS.
But people always say things like this, usually in comparison with a presidential system.
It makes no sense, as you're contrasting a person whom the majority would have to elect, and who could subsequently be voted out again, with a person who is inserted in the role - often planned and identified decades in advance - without anybody having any choice in the matter; and then they stay in the role until the day that they die.
The only way that anybody could possibly get the person out of the role - and understand that I am NOT advocating or recommending this in any way - would be to kill them; but even then, you would only see them replaced by their equally-unvoted-in son or daughter.
At least, in North Korea, they make a pretence of having an election, before officially 'crowning' the pre-determined ruler; we don't even bother doing that!
We love to consider ourselves a modern progressive democracy, but this is patently not the case at all.
