I’m not sure that many RF members really know what hard work is. Anne gets some kudos for turning up to 2 and 3 royal appointments a day regularly. And the late Queen did too of course. But also, they have very luxurious lifestyles and plenty of holidays. No one is cooking the dinner unless they want to. And no one is trying to find the time to scrub the multiple loos or iron a shirt for work last minute.
I take your point, but there are different ways of working hard! Personally I've always had a horror of precisely the sort of work that the RF (plus politicians, diplomats, actors and performers) do, so I consider that would be bloody hard!
I'm an introvert and NOT a night-owl, so the thought of having to constantly appear immaculate and be the centre of attention, make intelligent conversation (knowing I'll be pulled up for any gaffes), try to be photogenic and be probably at my best late in the evening....NIGHTMARE. When I have to do anything like this I have to de-pressurise the next day.
The privilege makes up for this, of course, but I still don't doubt they work hard in their way. They have to get it right, or there'll be hell to pay on a public stage so the pressure must be enormous. And some people are cut out for this and others - Charles, I think, is naturally an introvert and pretty shy - just aren't, but has to do his best anyway.
