The rise & fall of the working class: Laurie Taylor talks to Selina Todd, social historian at St Hilda's College, Oxford, about her sweeping study of ordinary British people between 1910-2010. Rooting her analysis in first person accounts from factory workers, servants and housewives, she reveals a hidden history full of the unexpected: How many of us know that cinema audiences once shook their fists at Winston Churchill? Also, US sociologist, Yasemin Besen-Cassino, discusses her research on 'baristas', the preparers of coffee across the urban world. She finds a group of affluent young people who'll work for poor wages if they're associated with a 'cool' brand.
