It's not something that we pay much attention to in Silicon Valley, but these price hikes are a direct result of mega-ag corporations shilling for price supports on corn, and lobbying to have corn used for ethanol (btw, corn is 10 times less efficient than sugar cane for this use).
The Congress (including Obama and Clinton) voted for the Farm Bill, and helped pass it. McCain slithered out with a "no show".
This is a pathetic display of ag money in politics, and a good review of just _one_ of the deleterious effects of catering to ag corporations.
This needs to stop.
