For whatever it is worth, I have an Argentina friend whom I respect very much. His work for many years has been importing and exporting. Before I saw this conversation I had talked to him about exports, etc., and he told me that the wheat shortage is directly due to government policy. Without going into detail here (I don't want to get into trouble with you guys) any time the government sets prices or limits a producer, he will stop producing. It is a fact of life! Economics is one of my avocations and I always watch with interest when there is some kind of price control. There is ALWAYS a resulting shortage and then incredible rising prices on those products. It is such a fact of economics it is amazing that people don't get it. Some cheer the government for limiting the "greedy merchants" when the real problem is government-caused inflation which raises prices. The problem is inadequate education in economics. It is rampant in the U.S. I don't know about South America but I am watching and trying to learn the markets and the mindset here.
