People don't eat feed corn....livestock do. And what the Midwest produces for ethanol production is feed corn.
Sweetcorn is grown by farmers that supply that market. "Roasting ears" usually have a low enough price, like 5 for a buck.
The fermentation process not only produces alcohol, it also releases nutrients in the remaining mash, a better animal feed than the original corn.
The mash is then dried and sold as a premium feed....giving at least two products from the very same corn crop.
Lowering animal feed prices = lower beef, pork prices at the market
Pork and chicken are typically cheap. Currently beef is expensive due to alleged the Dempanic fear in slaughter houses, and supply chain issues.
