SPEAKER_1: Last time we established that fiscal credibility is the permission structure that lets governments govern. Now I want to pull that into something domestic — because the same tension shows up inside the UK itself. SPEAKER_2: Right — and the domestic version is regional inequality. The UK ranks near the top of international comparisons of geographic economic inequality. That is not rhetoric. It is a structural fact with decades of data behind it. SPEAKER_1: How stark are the actual numbers? SPEAKER_2: In 2023, London's GDP per head was £69,077. The North East's was £28,583. And London's output per hour worked was 28.5% above the UK average. Output per job: 35.3% above average. London has held the top regional productivity spot continuously since the ONS series began in 1998. SPEAKER_1: So what is the mechanism? Proximity to London does not automatically make someone more productive. SPEAKER_2: The mechanism is agglomeration. Dense, well-connected cities generate productivity gains because workers, firms, and ideas cluster together — shared suppliers, labour pools, knowledge spillovers. Think of it like a network: each new node makes every other node more valuable. The Greater South East's share of all UK jobs rose from 38.9% in 2010 to 40.9% in 2022. And 51% of all publicly funded research and development was performed there in 2022 — a region with about 36% of the population. SPEAKER_1: Mm. And this feeds into health outcomes too, not just wages. SPEAKER_2: Dramatically. In 2021 to 2023, male healthy life expectancy at birth was 63.9 years in London but 56.9 years in the North East — a seven-year gap. In Middlesbrough specifically, the slope index of inequality in male life expectancy within a single local authority was 17.2 years. These are not abstract statistics. They represent real years of healthy life lost. SPEAKER_1: So the government's answer was Leveling Up — twelve missions, a White Paper in 2022. What did it actually promise? SPEAKER_2: The 2022 Leveling Up White Paper set 12 missions covering pay, employment, productivity, education, health, transport, housing, crime, and local leadership. The Leveling Up Fund was worth £4.8 billion — £4 billion for England, £800 million for Scotland, Wales, and Northern Ireland. Ambitious framing. But the IFS described progress as glacial, and some measures were going backwards. SPEAKER_1: Wait — backwards? SPEAKER_2: [short pause] Several measures. Between 2018-19 and 2022-23, further-education and skills completions in England fell 14% overall — nearly 20% in the lowest-skilled areas. The employment-rate gap between the best and worst-performing tenth of local authorities hit 21 percentage points in 2022-23, the widest since at least 2005. And public transport accounted for 39% of journeys in London but only 7% in the rest of England. SPEAKER_1: That transport figure is striking. If someone cannot reach a better job because the bus does not run, the productivity gap becomes self-reinforcing. SPEAKER_2: That is precisely the trap. And it is why infrastructure alone cannot close the gap. The key idea is that a single rail line cannot level up a region if skills, housing, planning powers, and local fiscal authority are not addressed simultaneously. The UK is one of the most fiscally centralized countries in the OECD. Local councils compete for competitive funding pots from Whitehall — critics argue that is inefficient and politically distorted rather than needs-based. SPEAKER_1: So genuine devolution means what, exactly? Because every government says it wants devolution. SPEAKER_2: [exhale] It means local authorities controlling meaningful shares of tax revenue — not just administering centrally allocated grants. Tax revenue per person in London was 88% higher than in the North East in 2019-20, up from a 66% gap in 1999-2000. That divergence is widening. Real devolution would let regions retain more of what they generate and invest it locally — in universities, hospitals, anchor institutions that keep skilled workers in place. SPEAKER_1: The takeaway, then — what distinguishes a genuine leveling-up strategy from a mirage? SPEAKER_2: Simultaneity and permanence. Infrastructure, skills, fiscal devolution, and anchor institutions have to move together, not sequentially. The regional ranking of wages changed very little over two decades of IFS analysis. That tells you the problem is structural, not cyclical — and structural problems require structural solutions, not one-off spending rounds.
