    There are several ways of retelling “Charlie and the Chocolate Factory”. In 2005 Hollywood focused on Willy Wonka, the factory’s owner, portraying him as a purple-gloved man-child. A new musical production of Roald Dahl’s children’s story at the Theatre Royal in London concentrates on the up-from-poverty fortune of Charlie Bucket, the boy who finds the golden ticket.

Tales of upward social mobility attempted or achieved are crowding the London stage. “Billy Elliott”, the story of a miner’s son who strives with the death of family strikes to make it as a ballet dancer, recently celebrated its four-millionth visitor. “Port”, an account of a Stockport girl’s attempts to escape her depressing origins, was a success at the National Theatre this spring. Last year “In Basildon” described strivers in the typical upwardly-mobile Essex town.

It is a respectable theatrical (and literary) theme, but it is being handled in a different way. John Osborne’s 1956 play “Look Back in Anger” showed a working-class man’s anger at the middle class he had married into. By the 1970s and 1980s writers were looking down their noses at social climbers, in plays like “Top Girls” and “Abigail’s Party”, in which a middle-class arriviste (暴发户) serves inferior snacks and the wrong kind of wine.

Social mobility moved away as a topic for a while, as playwrights like David Hare turned to examine carefully the state of the nation. Now it has returned—and is described much more sympathetically. Dominic Cooke, who directed “In Basildon” at the Royal Court Theatre, says this may be a delayed reaction to the collapse of state socialism in Europe.

A possible reason for the sympathetic tone is that upward mobility can no longer be taken for granted. In 2011 researchers at the London School of Economics concluded that intergenerational social mobility, assessed by income for children born between 1970 and 2000, had suspended. Another study, by Essex University academics, found matters had not improved during the crisis.

So it is fantastic fun to see people make it. Charlie Bucket does so spectacularly(壮观地). At the end of “Charlie and the Chocolate Factory” he is a pint-size entrepreneur(企业家), with an immigrant workforce of Oompa-Loompas to ensure he does not fall back down the social ladder.
