What annoys me is the cost and quality of their education. Yet they seem to academically and vocationslly achieve little.
Compare to Richard Branson's daughter (I forget her name). She had the best education money can buy, so actually learnt stuff at school and got great gates. Then did medicine to train to be a doctor even though she had no real need to have a Proper Job.
Granted, she did give up her medical career for a job with Daddy soon after qualifying. But my point is that her education wasn't wasted, she achieved highly. With all the resources and cost (to the public?) of the education of the Royals, they do on the whole seem to waste the educational opportunities they have.
