Do you live in the US? I would not say corn is a staple carb (not counting HFCS, but as a direct food replacing bread or rice) for most people. It is consumed directly as a vegetable (sweet corn) and as a staple in the form of cornbread, tortillas, and other cornmeal-based products but I would bet those don’t even form a plurality of starchy carb sources in the American diet, compared to wheat-based carbs like bread or even potatoes. It could be different in Mexico where corn tortillas are more commonly consumed, but in the US I don’t think corn is actually a common staple carb (again, not counting HFCS) at all.
You may wonder why I don’t count HFCS- that’s because it’s a sweetener composed of simple sugars whereas most staple carb sources are starches. It’s very common in processed foods, which Americans and Mexicans unfortunately consume way too much of, but is not exactly a staple most people have or use in their home cooking.
No; I'm from South America. In fact I was mentally comparing MX+USA with the situation here, it depends a lot on the specific region but usually there's a plurality of staple carbs (wheat, rice, potato, corn, yucca...). Cattle food, sugar and renewable fuel are taken up by other crops (soy and sugar cane).

That's good. I was mildly concerned about the situation because others mentioned corn farms subsidised by the government - relying too much on them for food would be risky, in the case of a plague.
