Of course they aren’t ‘our betters’. People may once have thought that, but I don’t think many do now. I don’t resent resent them at all, but I don’t think they are better than me.
I am much more troubled by the numerous people, much richer than the royals, who have made their money by dodgy business deals. I also resent show biz/pop music people who are ridiculously rich as a result of people’s taste for the mediocre and trivial. I know that reflects popular taste, but I still vainly hope that people will try to improve their minds by looking towards something better. I may as well give up on that one.
