Three words, my friend: "calories per acre".
Vegetables are not good calories sources; they are good nutrient sources. Grains are good calorie sources: your rice, your potatoes [not a grain], and especially your corn. Grains will yield 10-20 times the calorie per acre of vegetables. Grains are so insanely productive that, on a calories per acre basis, it is more land efficient to get your calories from corn-fed livestock than from vegetables.
Calories per acre are a big reason why vegetables cost more than meat. It is also why we grow different foods in different places. It is why basically all of our [the United States] potatoes come from Idaho: the volcanic soils there grow potatoes so well that it makes more sense to grow highly efficient potatoes in Idaho and corn in Kansas and ship them back and forth, because you'd get half as much corn in Idaho and half as many potatoes in Kansas.
