The entry point to this wiki for advocates and policymakers: the five most load-bearing pages, paths by what you need, all eight topic portals, and how we verify.
Start Here
This is a definitive, honestly sourced reference on Geoism — the idea that economic rents, beginning with the value of land and location, are created by the community and can be captured for public good. Land and the land-value tax are its core and best-evidenced case; the full scope reaches every kind of rent and every instrument for capturing it.
Whatever brought you here — building an argument, designing a policy, or checking a claim — the paths below get you to the strongest available evidence and the strongest counterargument, all cited.
If you have 5 minutes
The five pages that carry the most weight:
- Land Value Tax — the core policy: what it is, why economists across the spectrum take it seriously, and who really bears it.
- Economic Rent — the concept everything else rests on: value that accrues to a fixed factor rather than to effort or investment.
- Georgism — the political-economic philosophy tying it together, named for Henry George.
- Evidence Dashboard — the graded state of the evidence at a glance: what is Strong, what is Contested, and where the gaps are.
- Henry George — the person and the 1879 argument that started the movement.
By what you need
- To make the case → the Advocate's Arsenal for quotable, graded ammunition, and the Evidence Dashboard for the state of the proof.
- To design policy → the Policymaker's Brief for implementation records, design details, and defensible caveats.
- To face the counterarguments → the Objections Answered portal, where each objection gets its strongest version and an evidenced response.
By topic
Eight portals, each a curated way into a cluster of the wiki:
- Housing — land, rents, supply, affordability, speculation.
- Cycles and Crises — land speculation, the boom-bust cycle, and financial instability.
- Tax Design — incidence, neutrality, assessment, and how a land tax is actually built.
- Climate and the Commons — carbon pricing, resource royalties, and rent from the atmosphere and ecology.
- History and People — George, the single-tax movement, and the thinkers before and after.
- Case Studies — real jurisdictions, from Pennsylvania split-rate towns to Norway's oil fund.
- Objections Answered — the case against, steelmanned and addressed.
- The Rent Frontier — the contested edge: monopoly, finance, data, and IP rents beyond land.
