Hmm, I have the opposite perspective. Part of why I find the monarchy tolerable is the idea of an older and wiser statesperson to advise, encourage, and warn. Nothing against William, who is likeable, but he is younger than I am (and half the population) and doesn’t yet seem to have the wisdom or life experience of a typical monarch. (Or at least my image is a typical monarch, which is obviously skewed by my age/lifetime). I can imagine King Charles giving meaningful advice to Rishi Sunak. I’m not sure William is at that level yet.
I also like that we don’t have to worry about a child monarch, which is truly preposterous, should the worst happen. Especially in this digital age, I cannot imagine what a child monarch would face. Or even a child next of kin. Being an extra step away from the throne will hopefully afford them a little more peace.
Long story short, maybe it’s not a bad thing to have the norm become monarchs ascending in their 60s and 70s.
