Precisely my point. Maybe that's not a very future proof plan for Iowa? That sounds like at some point they are going to have to cut loose from the federal handouts.
It is apparently easier to make the subsidies continue forever than to consider growing alternatives.
Yep. When it comes to specialization farmers are not excluded. All crops, if their production can be mechanized, need specialized tools to farm at scale. In Iowa at least this looks like combines that are tooled for corn and soybean to allow for cycling the fields every few years.
