Well, part of what I was getting at is that it appears, from my layman's point of view, that WI's agriculture business is geared more toward crops that are easily industrialized and would require fewer workers in general.

e.g., a single worker operating a piece of machinery can harvest hundreds of acres of corn. A tomato, on the other hand, has to be hand-picked so that the fruit isn't damaged in the process. That requires substantially more workers.
