I have some of his dvds. What i remember him saying is that when you start, 90% of the plants are soil builders 10% food produces. In time, it switches and 90% of your plants are food producers and 10% soil builders. He also states that you can leave a system alone, and it will maintain itself. Come back years later and there will be food. It will naturally produce at a certain level. If you want to increase the yield, then you spend a day or two cutting and mulching to lift productivity. I can find the exact specifics of what he said in the video if necessary.
On permaculture, I see it as a system for the less simple minded

. We celebrate different life forms and what they have to bring to the table. We celebrate the circle of life. We celebrate the multivariable equations and creative expressions it allows. Depending on how you define wealth, I think Permaculture could be for 'the wealthy.' I would assume that once you have a good permaculture system in place, you live better than 95% of the people in the industrialized nations. You may not have a million dollar mansion, but you have all the nutrient rich food you could ever eat, a comfortable house to live in, and less worries about tomorrow. Appears you can make more per acre than conventional farming, becoming monetarily wealthy if you choose.
