Good grief, was there no adult in charge?
I presume much of the problem is the huge increase in ag prices from making subsidized ethanol instead of things to eat. The prices for grains are up as are the prices for grain derived products like corn based sweeteners. The food market must not have born them increasing their prices enough to compensate. Not to mention US manufacturers can’t switch from suddenly expensive corn based sweeteners to sugar because of the artificially high price of sugar government maintains to prop up the uncompetitive sugar cane farmers in the southern US. Also note I write this an anti-ethanol Iowan!
