Excerpt: We have two main problems with respect to land: How should it be used? How should rights in land be distributed?

But the voice of the future is heard only feebly over the din of the market place, and the public has a responsibility to speak on behalf of future citizens. The importance of land in the future will reflect three factors: What we want; the extent to which we create additional machines, factories, buildings, transportation, and similar tools to facilitate production; and our ability to devise new techniques of in- creasing output.
