Horses for courses
Public schools exist to create the material they need for the class they want to build. When Eton needed soldiers, it was a very harsh environment; later, when it needed shysters and chancers, it adapted successfully to produce Boris Johnson and David Cameron. The girls’ estate is no different – and in the 50s and 60s it needed hostesses and broodmares. The last thing you would have wanted them to emerge with was a bunch of O-levels.
