How can a sustainable local community (which is to say a sustainable local economy) function? I am going to suggest a set of rules that I think such a community would have to follow. I hasten to say that I do not understand these rules as predictions; I am not interested in foretelling the future. If these rules have any validity, it is because they apply now.

Supposing that the members of a local community wanted their community to cohere, to flourish, and to last, they would:

1. Ask of any proposed change or innovation: What will this do to our community? How will this affect our common wealth?

2. Include local nature -- the land, the water, the air, the native creatures -- within the membership of the community.

3. Ask how local needs might be supplied from local sources, including the mutual help of neighbors.

4. Supply local needs first (and only then think of exporting their products, first to nearby cities, and then to others).

5. Understand the ultimate unsoundness of the industrial doctrine of 'labor saving' if that implies poor work, unemployment, or any kind of pollution or contamination.

6. Develop properly scaled value-adding industries for local products in order not to become merely a colony of the national or the global economy.

7. Develop small-scale industries and businesses to support the local farm or forest economy.

8. Strive to produce as much of their own energy as possible.

9. Strive to increase earnings (in whatever form) within the community, and decrease expenditures outside the community.
