There seem to be few policy problems in Britain that “growth” will not solve. Backlogged and broken public services? We need growth to bolster tax revenues. National debt breaking £1tn for the first time? We need growth to make that sustainable. Rising worklessness and real wages that have not budged for 15 years? We need growth to fire up the labour market.
Growth has become one of those rare things, a policy panacea: promising to benefit almost everyone in society, leaving few problems out of its restorative reach. And for that reason, its pursuit has bent the political spectrum back on itself, with leaders at opposite ends meeting in agreement about its merits. For Sir Keir Starmer, it is the “defining mission” of his government; for Rishi Sunak, it was one of his party’s ill-fated “five priorities”.
The focus on growth is surely right. We need more of it. The challenge is how to create it. Today’s political leaders talk confidently about what is required. But this sense of assuredness is entirely at odds with the little we really know about growth’s causes.
