OK, as I have frequently mentioned, subsidized commodity prices have negligible impact on food prices. It seems the NCGA agrees.
NCGA’s analysis of the monthly Consumer Price Index (CPI) reports show almost no relationship between the corn prices and food prices. “The food index rose 0.3% in March, following larger increases earlier this year. Grocery store foods also rose less in March, largely reflecting a downturn in the index for fruits and vegetables.” [More] [My emphasis]
Tell me again. How does our alleged "cheap food policy" work again?
