Britain Built a State for a Richer Country

Britain did not become poor. It became slower-growing, older, more indebted, more housing-constrained and more expensive to run.

The state was much easier to sustain in a country with roughly 2% annual productivity growth, cheap industrial energy, affordable housing and a broad working-age tax base. What Britain got instead was closer to 0.5% productivity growth, faster demographic ageing, expensive industrial energy and housing rationed by consent.

Britain also tried to soften the demographic problem through migration. That expanded the working-age tax base, but it did not solve the underlying mismatch. Importing workers is not the same as importing productivity. If the country cannot build enough homes, grid capacity, transport, healthcare throughput or high-output jobs, population growth increases the load as well as the tax base. Britain imported population growth, not state capacity.

The promises held. The economic assumptions behind them did not. That is why the state no longer fits the country.

Britain is not communist. That was never the interesting comparison. The interesting question is how a market democracy with competitive elections, independent courts and private property rights came to record a larger share of national income through government than the People's Republic of China.

Recorded UK government spending was 44.1% of GDP in 2024. China's recorded figure was 33.0%. Vietnam's was 20.8%. China's true state footprint is larger than the fiscal line shows, but the point stands: Britain is not a small-state economy.

The OBR forecasts the UK tax-to-GDP ratio reaching 37.7% by 2027/28, the highest post-war level on record. The previous peak came in 1948/49, during reconstruction and the creation of the NHS. Britain is approaching that level not after a war but as the baseline operating cost of a peacetime state. The OBR's long-run projections show UK debt rising towards roughly 275% of GDP by the 2070s on unchanged policy, driven mainly by ageing-related spending pressures.

The state Britain built assumed several things would continue: steady productivity growth, cheap energy, expanding home ownership, a broad working-age tax base, tolerable infrastructure costs and enough political stability to reform what stopped working. Those assumptions no longer hold. Productivity growth has been weak for more than fifteen years. The population is older. Housing is rationed by consent. Industrial energy is expensive. Debt interest competes with defence. The public sector is larger, but the economy underneath it is less able to carry the load.

China and Vietnam appear here as calibration points, not models. Britain is vastly freer than either. The point is narrower: the old labels hide fiscal reality. Britain is a private-property democracy with a recorded fiscal weight sitting between two communist states on the chart because it built a state priced for a richer and faster-growing version of itself. UK public spending has been above 35% of GDP in every year since 1965, repeatedly returned to the 40-45% range and is back near its mid-1970s peak. No government has permanently reduced the fiscal settlement. Thatcher cut the rate of growth; she did not reduce the state. The direction has survived every manifesto.

Britain's public-sector headcount in September 2025 was 6.18 million. The NHS alone employed 2.07 million, a record. The civil service stood at around 550,000. By the usual definitions, this is not a lean state. The same state has 7.4 million people waiting for planned NHS treatment.

Britain almost certainly employs fewer state workers than China once state-owned enterprises and party-state structures are counted. The narrower point stands: a direct public payroll of this size, in a country spending 44% of national income through government, ought to produce shorter queues, cheaper rail and more housing than Britain currently manages.

The civil service grew from around 416,000 in 2016 to roughly 550,000 by March 2025. Both parties created new arms-length bodies while promising to rationalise the state. The total number of public bodies at all levels runs to an estimated 10,000.

Senior officials are formally under ministerial direction, but they are not replaced when governments change. When Liz Truss removed the Permanent Secretary to the Treasury in 2022, the Lords Constitution Committee ruled it an inappropriate breach of convention. He was gone. The civil service absorbed the Truss government, outlasted it and continued. Reviews merge, rename and occasionally abolish bodies. Of the 550,000 civil servants and 390,000 staff in classified arms-length bodies, none leave with the minister. What survives is the machinery, and the direction it was already moving.

The NHS waiting list in England stood at 7.4 million planned-treatment pathways in 2025; a non-urgent GP appointment in most areas takes two to four weeks. China's healthcare system offers no equivalent of the NHS settlement, and the comparison here is not about which country has better hospitals. It is about capacity: 7.4 million planned-treatment pathways in a country spending 44% of national income through the state.

UK rail fares are among the highest in Europe. The network achieves neither the efficiency of a full market nor the coherence of a state system. China's high-speed network covers 48,000 kilometres; Beijing to Shanghai, 1,300 kilometres, takes four and a half hours. China's rail is debt-heavy and built under conditions no democratic government would replicate. It appears here as evidence of what it looks like when a state actually decides to build something.

Housing is the loop made visible. The state controls the permission to build, uses that control to ration supply, then spends billions subsidising the gap it created — housing benefit, temporary accommodation, demand-side schemes. Britain is not mainly short of land, capital or demand. It is short of approvals in the places people want to live. The state built the bottleneck, maintains the bottleneck, and funds the consequences of the bottleneck.

Energy is the same contradiction. Britain wants net-zero moral leadership and an industrial base capable of sustaining it. UK industrial electricity prices are among the highest in Europe, reflecting a mixture of wholesale exposure, network costs, policy levies and a gas-dependent system that was never replaced. Expensive industrial energy is not a side issue; it is one reason the productive economy that is supposed to sustain the state is under pressure.

The private sector is not an infinite fiscal quarry. Higher employer National Insurance, fiscal drag, steep marginal rates and rising minimum labour costs can raise revenue in the short run while weakening the productive base that has to fund the state over time. The OECD recorded the UK as having one of the sharpest rises in labour taxation among rich countries in 2025-26. A state that becomes expensive enough starts to damage the economy it depends on. The direction of travel is not comfortable.

Every British general election since the mid-1970s has offered a choice between more state and less state. In fifty years, no government has permanently changed that direction. Spending has returned to the 40-45% range and is back near its mid-1970s peak. Both parties have presided over the same trajectory and neither has explained why so many visible outputs remain poor as spending rises.

The parties differ on the margins (tax rates, welfare conditionality, labour law) and those differences are real. They operate within a fiscal envelope that has expanded regardless of which party held it.

Britain is vastly freer than China, better governed than Vietnam, and protected by a rule-of-law system neither country provides. It also runs a larger recorded fiscal state than either of them. For that, it gets hospital queues, expensive rail, blocked housing, high energy costs and an administrative machine that survives every election.

The audit Britain has avoided is not ideological. It is arithmetic. What can this country afford? What can it deliver? What must be cut, built, taxed, deregulated, reduced or abandoned?

That audit has to include migration. Population growth cannot substitute for productivity growth. The question is not how many people Britain can add on paper. It is how many it can house, employ productively, move, power and treat.

Until that audit happens, Britain will keep running a rich-country state on a low-growth economy and calling the gap a funding problem.
