20/20 hindsight: How Britian lost control of its capital.
Year after year, the public services we rely on, from healthcare to transport, seem to be in a state of decline. Yet, government spending remains high, consistently hovering around 45% of GDP, aside from crisis-related spikes. On the surface, this should mean improved services or at least stability, as capital is invested or replaced. But reality tells a different story. Despite the heavy fiscal footprint, the UK government has recently had a negative net worth — meaning it now owes more than it owns. In this mini blog, we explore how Britain arrived at this paradox of high spending but low delivery, the policies that hollowed out public capital, and what it might take to turn the ship around.
A glance at government expenditure as a percentage of GDP might suggest a robust, active state, one committed to supporting its citizens. But this is an illusion. As the first chart shows, the UK has maintained a relatively steady expenditure ratio since the early 2000s, even during periods of fiscal tightening rhetoric. And yet, the second chart reveals a far more troubling development: for the first time in modern history, the UK government has slipped into negative net worth. This means that even with consistent spending levels, the state has been offloading assets (land, buildings, infrastructure) faster than it replaces them. In effect, we are renting back the country we used to own. The fiscal taps may still be flowing, but the pipes they fund are increasingly corroded, leased, or foreign-owned.
The roots of this erosion trace back to a decades-long trend of privatisation and outsourcing, initially sold as a way to make public services more “efficient.” From British Rail to water, energy, and even sections of the NHS estate, the UK has systematically sold off its productive public assets. What was once owned collectively (schools, roads, government buildings) has in many cases been transferred to private hands or leased back through schemes like Private Finance Initiatives (PFIs). These deals often saddled taxpayers with decades-long rental obligations, where the state pays far more over time than it would have through direct investment. This strategy may have balanced the books in the short term, but it hollowed out the government’s balance sheet. The result? A state that spends heavily, but owns little, a state that sells the roof to rent the rain.
While the UK leaned hard into privatisation, many of its peers took a more measured approach. Germany, for instance, maintained a strong industrial base supported by public and regional banks (Sparkassen) and a commitment to long-term capital investment. Essential infrastructure (like rail and energy networks) remains largely state-owned or closely regulated, with profits reinvested rather than extracted. In Japan, the state continues to invest in high-speed rail and resilient infrastructure, often at the expense of short-term fiscal surpluses but with long-term economic productivity in mind. Even France, often critiqued for its bureaucracy, maintains robust public control over utilities and transport, helping to cushion citizens from market volatility. These countries prove that retaining public ownership doesn’t equate to inefficiency — rather, it allows for coordinated planning and investment cycles beyond the whims of quarterly earnings reports.
At first glance, selling state assets may look like free money — cash now, less maintenance later. But in practice, it’s been anything but. When the government sells a power grid or a hospital wing, it loses control over not just the asset but its pricing, strategy, and long-term upkeep. Private operators, driven by shareholder returns, often prioritise cost-cutting and dividends over resilience or fairness. This has left the UK uniquely exposed to shocks: from volatile energy prices passed directly to consumers, to crumbling schools built with the cheapest materials under outsourced contracts. Worse still, the UK government’s net worth has now dipped into negative territory, as shown in the graph above, a rare status among developed economies. We are effectively renting our own infrastructure back at a premium, all while telling the public there's no money for investment. In truth, we didn’t run out of money. we sold the machinery that made it work.
This asset-light, short-term model doesn’t just fail on efficiency; it fails on fairness. The rentier structure the UK has created sees money flow from households to private monopolies and, increasingly, to international investors. When trains are delayed, energy bills spike, or water companies dump sewage while hiking prices, it's not the wealthy who suffer; it's working people who pay out of shrinking real wages. Council housing was sold off without replacement, forcing millions into private rentals that siphon income upwards. Even formerly free spaces, like city centres and parks, are increasingly commercialised or fenced off. The irony is sharp: in a country that once prided itself on public goods, the average citizen is now a tenant in their own economy, renting access to basic needs in a system they used to own.
We are now decades into a fiscal experiment that has failed to deliver long-term value. The numbers are stark: public net worth is negative, the quality of services is in freefall, and public frustration is boiling over. The UK’s selling spree may have propped up a few budgets in the 80s and 90s, but it hollowed out the state’s ability to act in the public interest today. Rebuilding won't be easy, but it’s not impossible. Strategic re-nationalisation, stronger regulation, long-term capital budgeting, and ending profit extraction from core infrastructure are all steps back toward economic self-respect. We need to stop treating public investment as a burden and start seeing it for what it is: the engine that makes prosperity possible. Shortsighted gains have cost us dearly, it’s time to start seeing clearly again, for the best time to plant a tree was 20 years ago but the next best time is today.
