James Graham's The Standard of Living arrives at the Theatre Royal Haymarket with a proposition that most economics-adjacent drama never attempts: that the interesting thing about John Maynard Keynes was not his equations but his conviction that economics existed to serve culture, leisure, and human flourishing. The play takes its title from precisely this idea — that living standards are not GDP figures but the texture of actual lives. The Guardian profile framing the play lays out the biographical architecture Graham is working with. Keynes as a Treasury official crossing wartime France to bid on Degas paintings at auction, successfully extracting £20,000 from the chancellor for impressionist art while shells fell. Keynes as a Bloomsbury insider, lover of Lytton Strachey and Duncan Grant, married to the Russian ballerina Lydia Lopokova. Keynes as the man who wrote Economic Possibilities for Our Grandchildren and imagined a future where the economic problem was solved and humanity lived like 'lilies in the field.' The material is extraordinary — the question is always what a playwright does with it. The central dramatic engine is the intellectual war between Keynes and Friedrich Hayek, which Graham stages as the defining economic argument of the twentieth century. Hayek's position: free markets self-correct over the long run, state intervention distorts. Keynes's counter, delivered in perhaps his most quotable line: 'In the long run we are all dead.' This is not a debate that resolves neatly, and Graham's choice to dramatise it rather than adjudicate it is the play's structural gamble. The audience must sit with genuine ideological tension rather than being handed a winner. What makes Keynes theatrically viable where most economists are not is the contradiction between his elitism and his humanism. Beatrice Webb's observation — 'He is contemptuous of common men, especially when gathered together in herds' — sits alongside his lifelong project of saving capitalism from itself for the benefit of everyone within it. He speculated recklessly on currency markets using his friends' money, lost everything when the pound fell in 1920, yet wrote with surgical clarity about the dangers of speculation overwhelming enterprise. He was, in the language of drama, a character who contained his own antagonist. The profile traces Keynesianism's arc from postwar dominance through the stagflation crisis of the 1970s, Thatcher and Reagan's Hayekian counter-revolution, and the 2008 financial crisis that sent policymakers scrambling back to The General Theory. Robert Lucas's grudging admission — 'I guess everyone is a Keynesian in a foxhole' — functions as both historical observation and as the kind of line a playwright would kill to have written. Graham inherits a story whose dramatic structure was built by history itself: thesis, antithesis, crisis, reluctant return. The deeper question the play poses, if the profile is any guide, is whether Keynes's vision of economics-as-means-to-leisure has been vindicated or defeated. Productivity has multiplied enormously since his death in 1946, yet the fifteen-hour working week he imagined remains fantasy. The accumulation of monetary wealth is more socially important than ever. His economics won the policy arguments in every crisis; his philosophy of what economics is for has been comprehensively ignored. That tension — winning every battle and losing the war — is the real dramatic territory. Graham is working in a tradition of British biographical drama that includes Peter Morgan's work on the monarchy and Tom Stoppard's intellectual plays, but The Standard of Living appears to be reaching for something more specific: using a single life to stage an argument about what an economy is actually for. Whether the play achieves this or collapses into biographical pageant is the question only the audience can answer. The material, at least, is first-rate.
