The trouble with people who think they can do anything is that they all too often start to think they can get away with anything. People who can hold the world in the palm of their hands are above ethics or criticism.
It's no wonder our elite - and if you still doubt we have an elite, take another look at the photo - has got a little out of touch.
Almost equally significant about the billboard is what it doesn't promise. It doesn't promise to make them good in any way. It doesn't promise to make them kind. Or generous. Or creative. It doesn't - and this is the bit I still marvel at - even promise to make them educated. It just promises to make them in control.
Why is this billboard in Ponsonby, that bastion of diversity and the alternative? Just kidding. Only the most out-of-touch observer could think this an uncongenial locale to flog an expensive education. Some of Auckland's most expensive houses. Some of Auckland's most fashionable fashion stores.
Still, it's quite a schlep from here to King's - about 7km each way to school in the Range Rover. Or in the buses now running from Ponsonby to the school each day, as advised in a wrongly capitalised sentence on the billboard.
But such imagery is not done without much forethought. Research will have been undertaken. This is an expensive exercise and you don't want to waste your money by sending the wrong signals.
So the creators of the billboard and their clients have discovered the sort of people who might be persuaded to send their children to King's want those children to be the ones running the show.
The people who can afford to live in Ponsonby are the people who can afford to send their children to King's, even if some have to get the bus because their mummies have to - gulp - go to work.
But can they afford to be so out of touch? And can they afford to breed a generation of selfish, entitled and arrogant young people, as promised in the advertisement?
