What is a Factory Farm?
Some people think of the heart wrenching scene in a Chipotle commercial where the cattle were in boxes and crying. This is nothing but a marketing ploy to persuade people who are uninformed to chose their products. In reality these farms can be owned by a larger corporation or business. Think of any fast food restaurant, there are multiple locations, but they are under the same name.
To many peoples surprise corporation farming is not a bunch of suit wearing men in a board room figuring out the budget for the year, it can also be a family. Many family's go corporate to create a save guard around themselves and their farm. While many people will look at this situation and only see large commercial farms, around 88% of farms are still family owned.
Consolidation of the farms in the U.S.
The basic answer to why we are seeing less farms and larger farms is that production on a large enough scale to make money is hard to do. It is hard to do for everyone, because the majority of the Ag products rely on a market price that changes. There is no guaranteed pay in these types of jobs. But when a larger business owns the ranch, the workers are going to get paid, and losses will not devastate the families tied to the ranch.
