The Longevity Imperative at the Lords: Turning ageing from fiscal drag to national strategy
- Turning longer lives into a global growth strategy
Britain should stop treating ageing as a looming liability and start treating longevity as a source of growth. That was the blunt message from London Business School professor Andrew J Scott at a House of Lords event, The Longevity Imperative: Health, Productivity, and Prevention in an Ageing Society, held on 14 October, where he argued that prevention, skills and age‑friendly work are the fastest route to higher productivity and lower health pressures.
Hosted by LBS alumnus, Lord Jitesh Gadhia (MSc, Management), through the Oliver Wyman Forum, with additional hosting by Rupal Sachdev Kantaria, Partner and Head of UK, Oliver Wyman Forum, the session was moderated by journalist Kamal Ahmed who paired Scott with GSK chair Sir Jon Symonds the timing was deliberate: life expectancy revisions are edging upwards, the government is reviewing the State Pension Age, the NHS has a new ten‑year plan prioritising prevention, and heavyweight economic bodies, the OBR, OECD and IMF, have each flagged the GDP gains from healthier, more engaged ageing.
“Demography isn’t destiny,” Scott told the room, stressing that the real story is not the number of older people, but how we age, and whether systems nudge people to stay healthy, skilled and in work. He contrasted a “silver economy” stereotype, cruises and care homes, with an “evergreen economy” built to sustain healthspan and participation across the life course.
Scott’s case has two planks. First, behaviour and incentives change when lives get longer. The UK’s official statistics office expects about half of today’s newborns to reach their early nineties; for those already in their sixties, the chances of reaching eighty have risen from around forty per cent to roughly three‑quarters over recent decades. With more future years likely, individuals and institutions have to invest earlier and differently, in health, in skills, in finances. Second, the macro upside is material if the UK keeps people healthy and employed longer. Most job growth in advanced economies already comes from over‑fifties. Halving the fall‑off in work between fifty and sixty‑five, Scott argued, could be worth around four per cent of GDP a year, gains hard to find anywhere else in macroeconomics.
He was equally direct about the health system: “We’ve built a brilliant system for keeping us alive when we’re ill, but not for keeping us healthy.” Waiting lists are the wrong target, he said; policy should set measurable health outcomes and allocate resources to achieve them. That requires shifting from hospital‑centric, late‑stage care to prevention and early intervention, and tying health decisions more explicitly to economic outcomes.
