There is something very ironic here. The purchasing power of food, at the farm level, amounts to little. By comparison, in 1939 8 hundredweight of milk would buy an acre of farmland in my county.
In 2008, 85.4 percent of U.S. households were food secure throughout the
year. Food-secure households had consistent access to enough food for active
healthy lives for all household members at all times during the year. The
remaining 14.6 percent (17 million households) were food insecure. These
households, at some time during the year, had difficulty providing enough
food for all their members due to a lack of resources. The prevalence of food
insecurity was up from 11.1 percent (13 million households) in 2007 and was
the highest observed since nationally representative food security surveys
were initiated in 1995.
