i promise you the only reason food prices are so high is because of techers stocking food. In fact, food prices didn't go up until I saw 3 techers started stocking and buying up an additional 50-75mil bushels a day. That is enough to cause a shift in market demand.
It is also the same time that all the top 100 countries are all at the range of escalating military #s.
The initial shock of market demand spike raised the prices and it stayed there since. It won't come down with any reasonable price change unless someone dump more than 75 mil additional bushels a day into the market.
