Levelling up

Sir: In making the case for social mobility, Lee Cain unwittingly endorses the classism he hopes to fight (‘Left behind’, 24 April). As the historian Christopher Lasch has argued, the canard of social mobility merely replaces ‘an aristocracy of wealth with an aristocracy of talent’. Far from being egalitarian, the concept is inherently elitist: it implies moving up, out or away from a class, town or profession condemned as undesirable.
