There are two additional reasons why food prices are soaring: First, the cost of oil has been skyrocketing, and as the price of oil rises, so too does the price of everything else -- including food. Second, there's a lot of market speculation going on right now. If you were wondering what those greedy imbeciles who wrecked the housing market with their sub-prime mortgage gimmicks and funds are up to these days -- well, they're speculating in commodities futures including wheat and corn. Among grown-ups in both the agriculture and financial communities, there's a spreading queasiness that this speculation is helping drive commodities futures prices through the roof -- and a growing consensus that Congress should start looking into this speculation, fast.
