A maxim used in the meat and dairy business (the original Just In Time supply chain) when a commodity's price drops below the cost to produce the commodity. You only have two choices, sell at a loss or let it rot in the barn.

Profit margins for meat producers are razor thin, between 1 and 5%. It does not, then, take much to drive prices below production costs. For several years now hog farmers have been faced with a "sell it or smell it" proposition.

In sum, bring back the McRib!
