My point is that if this is to make any sense, it has to mean that there's a continuous appreciation in the price of "beans." That figures: by virtue of the technical structure of production a certain non-basic (or class of non-basics) cannot earn the average rate of profit, at constant prices; but they _can_ achieve that rate if they are progressively appreciating relative to other commodities. Then my further point is that any commodity that is continuously appreciating relative to others is probably not long for this world. The demand will be choked off. Allin Cottrell
