| Corn in the US is heavily subsidized. It's why corn syrup is so prevalent in US foods, because the subsidies mean it's cheaper than any other sources of sugar. In the US, Iowa is the largest producer of corn [1] (producing nearly 40% more than the next, Illinois,) and thus the greatest beneficiary of those corn subsidies. Could we reduce those corn subsidies? No, it's politically nonviable, in part because Iowa has enshrined in its laws that it must have the first primaries in the US [2][3]. No candidate that has ever said anything against corn subsidies has won a primary. [1] https://www.cropprophet.com/what-state-produces-the-most-cor...

Corn isn't really subsidized, and iowa corn farmers are not the benefactors of the agricultural bills. Cattle producers and chemical corporations are subsidized, and the way they're subsidized is by a myriad set of policies which encourage grain prices to stay very low. This makes cattle feed cheap and corn and soy inputs to chemical plants cheap.
If the price of corn doubled, farmers could afford to pay their mortgage and taxes without trying to extract every bit of possible yield. But then the price of beef would go up and the profits of 3M and Dupont would go down, and that's a far more powerful force than farmers in Iowa.
