No food is cheap because of our vast productive land and technology. I'm not denying that subsidizes don't exist. You can't just make general statements.

If you added up the entire market for all retail and food services-- we are talking trillions of dollars a year in sales. The subsidizes are small. Think restaurants, grocery stores, food processing, etc that are all in this category.

Food is also cheap the New Zealand, who doesn't subsidise at all. The US has fantastic soils, good weather, buckets of cheap capital, and an awesome transportation network (both natural and artificial); that's why food is cheap.
