I have participated in this discussion of commodities being a zero sum game for a number of years and have always contended it is not such. It is zero sum if you add in the consumers but it is not without them. Imagine there are three people on the planet. A consumer, a producer and a distributor. The producer generates the commodity for a price of $1 and sells it, through a commodity contract that is ultimately delivered. The producer sells for $2 and produces $1. Over a period of time the price of the commodity rises to $3. The supplier sells his delivered commodity to the consumer for $3, making a profit of $1. Over the duration of the trades the producer makes $1, the seller earns $1. The consumer pays a higher price and may be considered the loser to balance the scales of a zero sum game. However, the participants in the commodity transaction both made cash. Not a zero sum game.
