That is likely due to available supply and aggressive marketing. While US beef prices are middle of the road compared to the rest of the world, it’s much cheaper when compared to average income and GDP. (I am not an economist by any stretch, but that makes sense to me.)
If there are two things that we Americans have massive supplies of, it’s cattle and corn. (And guns. You can’t really eat guns though.) From that perspective, it kinda makes sense that we have those as staples in our diets.
Cattle and corn aren’t resources like oil or metal. They have to be produced in order for there to be a surplus. If we have a massive supply of cattle and corn, that’s because somebody grew a massive supply of cattle and corn. Farmers don’t have to grow cattle and corn; they can choose to grow other things.
Not really, maybe in Asia milk isn’t so popular but it’s a staple for people of all ages in many, many countries, not just the US.
