I laughed at loud, as I trust that you did, when I heard Cameron trying to make out that he had the first idea about the price of bread, milk, butter and eggs. He should be presented with a loaf of bread, a pint of milk, a pound of butter and a dozen eggs, and asked to say which was which. I bet he couldn't.
I also confidently assert that he has never paid rent. And anyone may see that there is no mortgage on any of his three houses, two of which are of course exempt from Council Tax.
All in all, it is no wonder that he isn't proposing any actual changes.
Concerning Oxbridge, to which Eton sent 95 people last year, I recently asked someone how good the ninety-fifth best Etonian in his year could possibly be. Good enough to be Leader of the Conservative Party, clearly.
