Why UK Growth Per Person Has Stalled, and What Comes After

The November 2026 episode of Radical Thinking with Aditya Chakrabortty arrives at a moment when the United Kingdom's growth debate has exhausted its familiar vocabulary. Successive administrations have cycled through fiscal expansion, austerity, deregulation, Brexit, and levelling up, yet output per person has remained broadly flat since the 2008 financial crisis.

Economists Karel Williams and Sukhdev Johal join the programme to argue that this is not a policy failure awaiting correction but a structural condition demanding a different question entirely.

Their central claim is precise and uncomfortable: the pursuit of growth has become a political ritual rather than an economic strategy. Williams and Johal, both affiliated with the Foundational Economy Collective, contend that higher or lower public spending, regulatory reform, and territorial rebalancing have all been tested and none has restored the pre-2008 trajectory.

The podcast therefore shifts register, asking what a credible life after growth might look like for ordinary towns and suburbs rather than how to restart an engine that may no longer exist.

This analysis examines the episode's argument, situates it within the wider stagnation literature, and weighs its implications for fiscal policy, local economies, and the political contract. It also tests the thesis against available data on productivity, real wages, and regional divergence, because the strength of any post-growth case rests on whether the stagnation diagnosis survives empirical scrutiny.

TL;DR A new Radical Thinking episode featuring Karel Williams and Sukhdev Johal argues that UK growth per person has stalled structurally, not cyclically, and that spending levels, deregulation, Brexit, and levelling up have all failed to restore it. The economists, working within the Foundational Economy Collective, propose that pursuing growth is now unrealistic and that political attention should shift to the quality and security of everyday life in towns and suburbs. The discussion reframes stagnation as a governance problem rooted in extractive business models and neglected foundational services rather than a simple shortage of investment or ambition.

The Stagnation Diagnosis: Why Growth Per Person Stopped Responding to Policy

The episode's analytical core is a distinction between aggregate GDP and GDP per capita, and the evidence favours the sceptics. UK output per head grew roughly 2.2 percent annually in the two decades before 2008; since then it has averaged well below 1 percent, with several years of outright contraction. Population growth has masked weak productivity, meaning headline GDP can rise while living standards stagnate.

From Cyclical Slump to Structural Plateau

Williams and Johal reject the framing of stagnation as a temporary shortfall that competent management could reverse. Their argument is that the mechanisms which once transmitted investment into productivity gains have degraded, so stimulus now inflates asset prices and imports rather than domestic output. This distinguishes their position from orthodox Keynesian calls for demand expansion.

The productivity puzzle is well documented. UK output per hour trails the United States, Germany, and France by margins that have widened since 2008, and business investment as a share of GDP has consistently lagged the G7 average.

These are not the signatures of a cyclical downturn but of a persistent, economy-wide drag on capital deepening.

Regional divergence reinforces the point. London and the South East generate productivity levels far above the national mean, while parts of Wales, the North East, and the Midlands sit closer to levels last seen in the 1990s.

Levelling up was designed to close this gap; the episode contends it has not done so at scale.

The Foundational Economy as Analytical Lens

The Foundational Economy Collective supplies the episode's theoretical scaffolding. Its research identifies a set of mundane but essential sectors—water, energy, food distribution, health, care, and retail—that employ a large share of the workforce yet operate under extractive ownership models. These sectors generate reliable demand but weak productivity and investment.

Williams and Johal have applied this lens to the water system in England and Wales, documenting how financialised ownership diverted capital toward debt servicing and dividends rather than infrastructure. The same pattern recurs across utilities and care provision, where shareholder returns take precedence over service quality and workforce stability.

This matters for the growth debate because it relocates the problem from macroeconomics to corporate governance. If foundational sectors are structured to extract rather than reinvest, then aggregate demand stimulus will not translate into productivity gains. The bottleneck is institutional design, not the level of government spending.

Why Brexit, Deregulation, and Levelling Up Underdelivered

The episode treats each policy lever with the same scepticism. Brexit reduced trade intensity and increased friction for exporters, with the Office for Budget Responsibility estimating a long-run productivity cost of around 4 percent. Deregulation has not visibly raised business investment, which remains below pre-2016 trend.

Levelling up allocated funding through competitive bidding processes that favoured already-capable local authorities, leaving weaker councils further behind. The net effect has been to redistribute modest sums without altering the underlying geography of investment, which continues to concentrate in London and the South East.

Higher spending under recent governments raised public investment modestly, but much of it flowed into capital projects with long lead times and limited immediate productivity effect. The economists' conclusion is that none of these instruments addresses the structural composition of the UK economy.

Life After Growth: What Towns and Suburbs Would Actually Need

The episode's constructive half is more speculative but analytically useful. If growth per person cannot be restored through demand management, then policy must focus on the resilience of everyday life: secure housing, reliable utilities, affordable food, functioning care, and decent local employment. These are the domains the Foundational Economy Collective has mapped in detail.

Redefining Success Beyond Output Metrics

Williams and Johal argue that GDP per capita is a poor proxy for welfare because it counts activity without distinguishing between investment and extraction. A water company that pays dividends while leaking sewage registers as economic output; a care provider that pays poverty wages registers the same. The metric is blind to quality.

Alternative frameworks exist. The OECD Better Life Index, Scotland's National Performance Framework, and New Zealand's wellbeing budget all attempt to measure outcomes rather than throughput. The episode does not endorse a specific index but insists that political success be judged on lived conditions rather than aggregate expansion.

This is not an argument for stagnation by design. It is a claim that the pursuit of a growth rate that has not materialised for eighteen years has crowded out attention to problems that are tractable now, including housing supply, utility governance, and local service capacity.

The Foundational Economy in Practice

Concrete proposals flow from the collective's research. Municipal ownership of energy generation and retail, as seen in Bristol and Wrexham, keeps surplus within local economies. Public procurement anchored in foundational sectors can stabilise wages and supply chains without requiring national growth.

Water reform offers the clearest test case. The episode's contributors have documented how debt-financed ownership structures diverted capital from infrastructure. Renationalisation or mutualisation would redirect those flows toward maintenance and resilience, producing measurable service improvements independent of GDP growth.

Care and health provision follow the same logic. Workforce shortages and provider failures stem from ownership and funding structures that reward extraction. Restructuring these sectors would raise employment quality and service reliability even in a low-growth macroeconomy.

Political Feasibility and the Cost of Living

The episode acknowledges that post-growth politics faces a credibility problem. Voters experiencing a cost of living crisis want immediate relief, and arguments about structural stagnation can sound like resignation. Williams and Johal counter that foundational reform delivers tangible benefits faster than growth strategies with decade-long horizons.

Utility renationalisation, care wage floors, and council housebuilding produce visible results within electoral cycles. They also redistribute income toward lower-decile households, whose spending propensities are higher, generating modest demand effects as a by-product rather than a target.

The political risk is fiscal. Public ownership requires upfront capital, and the UK's fiscal headroom is thin. The economists argue that the counterfactual—continued extraction, service failure, and emergency bailouts—carries higher long-run costs, a claim supported by the water sector's recent refinancing episodes.

Testing the Thesis: Evidence, Objections, and What Comes Next

Any post-growth argument must survive empirical challenge, and several objections deserve serious weight. The most substantive is that the UK's stagnation reflects specific policy errors—weak investment, planning constraints, skills shortages—rather than an inherent limit to growth. On this reading, the diagnosis is correct but the prescription premature.

Productivity, Investment, and the Missing Capital

Business investment in the UK has averaged roughly 10 percent of GDP since 2016, below the G7 mean of about 13 percent. Closing that gap would require sustained capital deepening, which historically correlates with productivity gains. The stagnation thesis must explain why this channel has failed.

Williams and Johal's answer is that investment incentives are misaligned. Financialised ownership structures reward short-term distributions over long-horizon capital projects, and the UK's equity market pressures reinforce this. The result is a persistent investment gap that no tax incentive has closed.

This is testable. If ownership structure drives underinvestment, then publicly or mutually owned firms should exhibit higher capital expenditure ratios. Evidence from European utilities and municipal energy providers broadly supports this, though selection effects complicate clean comparison.

Objections from Orthodox Economics

Mainstream economists would counter that the UK's problem is insufficient capital accumulation, not an inherent growth ceiling. Planning reform, pension fund investment in productive assets, and skills policy could plausibly raise the growth rate. The episode does not refute this directly.

Its response is pragmatic rather than theoretical. Even if growth could be restored, the political record suggests it will not be, and policy cannot wait indefinitely for a strategy that has failed for eighteen years. Foundational reform is therefore justified as insurance, not as a rejection of growth.

This framing is strategically shrewd. It lowers the burden of proof: the economists need only show that foundational reform improves welfare under stagnation, not that growth is impossible. That is a far easier empirical claim to sustain.

Implications for Policy and Political Strategy

The episode's practical implications are clear. First, fiscal policy should prioritise foundational sectors over broad stimulus, because the transmission mechanism from demand to productivity is broken. Second, ownership structures matter as much as spending levels, which reframes nationalisation debates.

Third, local economic strategy should focus on procurement, municipal enterprise, and service resilience rather than attracting inward investment through tax competition. Towns and suburbs gain more from stable utilities and care provision than from speculative growth deals that rarely materialise.

Finally, the political contract requires honesty. Governments that promise growth they cannot deliver erode trust, and the episode's contributors argue that a credible offer of security and service quality would be more durable than another growth pledge destined to disappoint.

Conclusion: A Debate That Has Moved Beyond Growth

The Radical Thinking episode does not settle the growth debate, but it reframes it productively. By demonstrating that every major policy lever has been tried without restoring growth per person, Williams and Johal shift the burden of proof onto those who promise a return to trend. The stagnation diagnosis is empirically credible.

Their constructive proposal—foundational reform focused on ownership, procurement, and service quality—offers measurable benefits independent of aggregate growth. Whether or not one accepts the post-growth framing, the emphasis on institutional design over spending levels is a genuine analytical contribution to a debate that has grown stale.

The political challenge remains substantial. Foundational reform requires upfront capital, delivery capacity, and a persuasive narrative that security is not resignation. But the alternative—another decade of growth pledges that fail—carries its own costs, measured in eroded trust and deteriorating public services.
