Britain's housing dysfunction is not primarily a supply problem — it is a tax-architecture problem. That is the argument threading through the Guardian's analysis of John Healey's first budget, and it is one the government appears to understand intellectually but lack the political will to act on. Oxford academic John Muellbauer, who has spent four decades studying the system, calls UK housing 'one of the most dysfunctional in the world,' tracing its failures to land-use regulation, financial regulation, and property taxation working in concert to entrench extraction. The budget offered scattershot measures: a revamped help-to-buy scheme for new builds, modest council housebuilding funds, an extra tax on landlords, and homelessness pledges. The Resolution Foundation labelled it 'more about politics than economics.' The structural question — how to stop housing functioning as a wealth-storage vehicle rather than shelter — went unanswered. Help-to-buy, in particular, is demand-side stimulus into a supply-constrained market, a recipe for inflating prices and enriching developers. The reform that matters is council tax. The current banding system, frozen on 1991 valuations, is a regressive artefact. Muellbauer and others have proposed replacing it with an annual percentage levy on current property value — say 0.5% — while abolishing stamp duty entirely. A £150,000 home would pay £750 per year; a £3m home would pay £15,000. Rachel Reeves's mansion tax on homes above £2m is directionally correct but structurally insufficient because it retains the banding system rather than establishing a continuous revaluation process. The political obstacle is precisely identifiable: professional-class owner-occupiers in London, the south-east, and affluent suburbs around major cities. A £1.5m home under a 0.5% regime would face a council tax bill of £7,500 — more than double current rates. This lobby group, both working and retired, is the constituency most governments are terrified of alienating, even though the stamp duty abolition that accompanies the reform would benefit them enormously when they sell. The generational transfer mechanism is perverse. Gen X uses parental property wealth to fund social care for their parents and housing deposits for their children — a circular system where housing equity substitutes for adequate public provision and wage growth. The leasehold-freehold split further stymies investment in energy efficiency and solar panels because ownership of the improvement is contested. Developers, incentivised by weak planning regulation and ill-targeted subsidies, build on flood plains and erect poorly ventilated towers. Treasury minister Torsten Bell, whose book describes Britain's 'housing omnishambles,' is among those inside government who grasp the structural problem. But influence has not translated into policy. The budget's biggest bet — devolution from London to the regions — addresses governance structure, not incentive structure. Bad policy decisions can be made locally just as easily as centrally; what changes outcomes is a permanently reformed tax landscape. The 20-year trajectory without reform is clear: housing continues to function as a wealth-concentration mechanism, intergenerational mobility declines further, stamp duty continues to freeze transactions, and the UK's chronic underinvestment in productive capital — as opposed to property — persists. Every help-to-buy iteration inflates the asset further. The disease is not a lack of building; it is a tax system that rewards hoarding.
