Very sad that after a life trying to be a useful person and succeeding brillantly, there are still people who consider Prince Charles to not be much more than an animal.... In which world do you live?
How many people did you or Hilary Mantel help out of the gutter into a new, meaningful life? But no, because a lot of people want to look at the Royals they have no value? How shallow a view is this?
No one, neither myself nor Hilary Mantel, is saying that the royal family are literally animals. I hope you have heard of these things called metaphor and simile; a famous example is Shakespeare's "All the world’s a stage,
And all the men and women merely players". He certainly does not mean the earth is literally a stage and we are all literally actors.
The animal metaphor refers in particular to the way the royal family are now largely treated as animals in a very gilded zoo, there for the media to gaze at, pick over and scrutinise. This probably also applies to all of us here on this forum to some degree too, for even if it is in kindness, it is still a similar relationship.
As to the charity thing, their active engagement in charity is a relatively recent phenomenon, largely to do with them trying to find something to do now that they lack the former tasks of royalty to undertake. Of course, this charity work is appreciated and good for society and I'm sure some of them truly enjoy helping people. But many people in the world do charity work, and those who don't, well perhaps they lack the time because they work full time, earning a living to support their families. And to justify the royal family simply because of the charity work they do is truly simplistic. For example, if we ceased to find the royal family via tax payers this money could go straight to charities or be used to leverage fund raising for charities via other means. I am not suggesting this be done, merely that the same kind of societal benefit could be created in numerous ways.
(And just in case you wondered, I am a volunteer surf life saver in addition to my full time job. So, I haven't helped people out of the gutter; I've literally saved them from death. I would also add that Hilary makes a huge contribution to society via her art which enriches people's lives. Not that any of this should matter when trying to engage in a rational, adult discussion about an interesting topic.)
