Objection: if LVT is so good, why has almost no one adopted it?

The Objection

It is the most common challenge a newcomer raises, and it is a serious one. If land value taxation is as efficient and fair as its advocates insist — endorsed across the spectrum from Adam Smith to Milton Friedman (who called it the "least bad tax"), the rare policy "all economists agree on" — then its near-total absence from the modern tax system is itself damning. This is a revealed-preference argument: across a century and a half and dozens of democracies that were free to adopt it, essentially none runs a pure or even dominant land value tax. Either the theoretical case is quietly missing something real — assessment is harder than admitted, the transition too disruptive, the revenue too thin — or the single tax is a perennial economists' daydream that founders on contact with reality. A policy the experts love but no electorate keeps should make you suspect the experts.

The Strongest Form

The sharpest version does not rely on mere rarity; it points to retreat. Where the pure tax has been tried, it has repeatedly been rolled back:

• The UK, twice. Lloyd George's 1909 land-value duties were repealed in 1920; Philip Snowden's land value tax in the Finance Act 1931 (Part III) was suspended and then repealed by the Finance Act 1934 before a penny was ever collected.[2]
• Altoona, Pennsylvania. The one US city to rely on a land-value-only tax (from 2002; the sole US city on pure LVT by 2011–2016) repealed it in 2016, having "foundered on the realities of administrative complexity and politics."[1]
• Pittsburgh abandoned its long-running two-rate (split-rate) system in 2001 after a botched county-wide reassessment (Pittsburgh).

Adoption, the objection concludes, is not merely rare — it is unstable. That is harder to explain away as landlord obstruction; it looks like the policy failing its own field tests.

The Response

The reply is not to deny the pattern but to read it correctly.

1. It is adopted far more than the objection assumes — just rarely in pure form. Split-rate and site-value systems operate in ~20 Pennsylvania municipalities; Denmark has levied grundskyld (a land tax) for over a century; Estonia has run a pure land tax since 1993; Australian states (New South Wales) tax site value; Singapore and Hong Kong capture enormous land rent through public leasehold; and Taiwan built a land-value and increment tax into its post-war settlement. The honest description is "widely adopted in diluted form, rarely in pure form" — exactly what one expects of a reform that must be grafted onto entrenched property-tax institutions rather than built from scratch. Andelson's definitive country-by-country survey, Land-Value Taxation Around the World, catalogues these diluted adoptions across dozens of jurisdictions — the empirical answer to "almost no one uses it."

2. "Good but unadopted" is the norm in tax policy, not an anomaly. The benefit of an LVT is diffuse (a slightly more efficient economy) while its cost is concentrated on a wealthy, organised, and highly motivated group — the textbook Olsonian collective-action problem, sharpened by the fact that current owners paid market prices and would bear a one-time capitalised loss (transition wealth shock). Michael Hudson's catalogue of Henry George's political critics documents the specific historical mechanism: twelve political attacks that isolated the single-tax movement from socialists, organised labour, and academic economists after 1887 — a coalition failure, not an economic refutation. Economists also broadly favour carbon taxes and abolishing the mortgage-interest deduction; those are rare too. Non-adoption tracks political feasibility, not economic merit — and by the objection's own logic one would have "refuted" congestion pricing, near-nonexistent until the 2000s and now spreading.

3. The rollbacks have specific, non-fatal causes. The UK duties died on valuation-administration problems and changes of government, not on any demonstration that the tax did not work; Altoona's and Pittsburgh's reversals followed assessment failures — which is an argument for better mass-appraisal institutions (can land be assessed?), not against taxing land value. A tax base does not become unsound because the registry valuing it was mishandled.

Net Assessment

The objection lands a real hit. The gap between economists' endorsement and real-world adoption is genuine and demands explanation, and the rollback record shows the transition and assessment problems are not merely theoretical — the pure single tax remains largely untested at national scale, which should temper anyone's confidence about a 100% LVT. But the revealed-preference inference overreaches. Diluted adoption is in fact widespread; the barrier to the pure form is precisely the concentrated-interest politics that theory predicts, not a hidden economic flaw; and the specific failures trace to assessment administration and political turnover rather than to the tax base misbehaving. The fair verdict: LVT is under-adopted relative to its merits for reasons political economy explains well — and its full form is a promise the historical record has not yet been allowed to test.
