Say what you like about the posh – they know their place. Equipped from an early age with a sense of entitlement, they also have access to the oldest and most powerful social network there is: call it what you will, but the old boys' network remains, and you’d be hopelessly naïve to think otherwise. Where would our current prime minister be without it? Tony Parsons, who, as a working-class boy made good, is among a pitifully declining breed, thought he knew: “If David Cameron had gone to a comprehensive school he’d be lucky to be digging ditches,” he spat. That seemed unduly harsh, but after absorbing a few of the stats in last night’s Posh and Posher, it seemed fairly clear what Cameron’s “life chances” – to use old New Labour parlance – would have been, and it certainly wouldn’t have included running the country.
