| I think tradition is certainly part of it, but I think that take misses some important nuances. A few: - agriculture isn't necessarily fungible. Land that is used for one product isn't immediately capable of being used for another, or at the same value (monetarily or calorically) - A large part of corn production is used for feedstock. That means there would be systemic issues in the production of meat if it had major disruptions. That's another reason why you can't just swap corn for meat production. - subsidies sometimes trade efficiency for stability. This isn't always a bad thing. A volatile market can make farmers lose their hat. A significant amount of farmers are generational, meaning there aren't a lot of people starting out unless they grew up farming. - corn isn't just about food. Part of the national security element is fuel (ethanol). Again, recognizing the inefficiencies, this is more about stability. Other agricultural products can be used for fuel (e.g., soybeans for diesel) but the distribution of fuel needs and agricultural capacity is not in their favor. - I'd put this in the "tradition" bucket but there are political concerns. Politicians have to place nice with places like Iowa because of how political primaries are structured. |
Key word being "immediately". That's right, but substitutions do exist. Hence, growing pains.

Globally, soybeans are more often used, and these can (and do) grow in the US. Notwithstanding, you can just keep growing corn without subsidy - meat prices would go up. That could be politically contentious, but less total meat consumption could lead to better health outcomes.
> subsidies sometimes trade efficiency for stability
Leaving aside the question of balance, pros and cons:
Farmer stability is not inherently contingent on corn subsidy. Even if we wanted to keep subsidies as a constant, you can subsidize something else.
> part of the national security element is fuel (ethanol)
This doesn't require subsidy. The US produces more than half of the world's ethanol fuel. Notwithstanding that, fossil fuel extraction has also grown through fracking. I don't see the security angle at all.
