“Farms need cheap farmworkers.........”
I seriously doubt that’s the reason. Iowa farmers grow corn and wheat. Neither needs a big labour force to “pick” either.
They have machines called “combines” to reap the crop.;)
More likely its the hog slaughterhouses needin the cheap labour.
I know, it’s the hog farmers......I was being general........
You’re absolutely correct. There are also large dairy farms that use them but crop farmers don’t need them. That’s why they’re more concentrated in certain areas.
