Henry George is claimed, by Robert Heilbroner, to have believed in this single step to permanent perfection. We believe that his single tax on land is part of a larger paradigm of taxing problems to subsidize solutions (or at least unburden them). A single tax on land area is perfect for an agricultural economy, especially if it focuses on taxing too much land per person. But then storehouses and warehouses became more important than land, so we needed to tax excessive volume per person. And then the contents of the houses, whether for storage or business or just plain living became more important, so we needed to tax excessive mass per person. And now the activities of what's in the buildings has become most important, so we need to tax the worktime of everyone in those buildings. This is where Timesizing's single tax on excessive worktime ("overtime" per job or "overwork" per person) comes in. The whole progression just follows the paradigm of dimensions in one of the introductory booklets to Timesizing. And it doesn't stop at balancing worktime or employment.
