So what makes someone like Boris Johnson more fitted to lead, having been voted into office democratically?
Happy to remind you of the 5 questions Tony Benn said we should ask of people in power.
What power have you got?”
“Where did you get it from?”
“In whose interests do you use it?”
“To whom are you accountable?”
“How do we get rid of you?”
Boris Johnson, Liz Truss, may have been terrible leaders. But we knew exactly what their power was, where their power came from, in whose interests they were supposed to use it and to whom they were accountable. Indeed, when that power was abused through incompetence in the case of Truss and lack of integrity in the case of Boris, it was clear that question 5 had to be asked, and they were got rid of. Elections and the opposition party system also perform the checks and balances function needed to hold politicians accountable and to get rid of them.
The monarchy in contrast apparently gets power (and influence) from being anointed by God in what is now a minority but still Establishment based church, all based on an ancient rule that only persons of a certain bloodline, and therefore members of only one race, and until recently, only one sex, who must be the first born children, no matter their suitability for the job, can be monarchs.
The monarchy appears to be interested mainly in the self-preservation of those first born family members considered to matter most to the institution while sacrificing others (and this was the case long before Harry was even born), seems to focus on pursuing its narrow interests eg not paying inheritance tax or being subject to racial discrimination laws while talking of duty but not upholding systemic equality because b its nature, sitting at the apex of eh aristocracy effectively means endorsing class privilege based on primogeniture. The family appears to be only accountable to the media, who in turn use it to make money. It is such a corrupt arrangement, made worse by the fact that it is run by people with dysfunctional ideas and values and who seem to be pretty horrible to each other, and, to make it worse, Tony Benn's final question does not apply to them because, unlike Boris, you can't get rid of them.
I get that the monarchy means a lot to a lot of people, but Charles has the right idea about reform. But I don't think the reforms he has in mind will go beyond the cosmetic needed for, yes, you guessed it, self-preservation.
