I remember hearing and/or reading that the US government burned corn (or destroyed it) at some point. This was not because there was anything wrong with the corn, but rather because by buying it they could sustain higher prices for the corn (pleasing corn farmers); as presumably their reserves were already full, it was disposed of.
I can't find anything that substantiates this recollection. The closest I can find is stories about the US government paying farmers to not grow crops. Has anybody else heard the same story of the government actually destroying corn? Can anybody point me to a source?
