As an Iowan, I live in a state where pigs outnumber people by more than six to one. What would happen if they revolted? In his 1945 work, Animal Farm, George Orwell explores this possibility with the story of an animal revolt led by pigs on an English farm.
Animal Farm is an allegory of the Russian Revolution of 1917 and the events that followed. Orwell very cleverly portrays various types of people and the lies, schemes, and tricks used by evil leaders to retain popular support. When those in power (whether pigs or people) rule for their own selfish ends, even the most well-intentioned, hardworking, and loyal suffer.
This book takes only a few hours to read and has many good insights. It's available in printed format at libraries and bookstores, and as a free ebook.
Do I foresee a similar revolution happening in Iowa? Not during the winter months. Iowa pigs are dependent on the warm climate of the propane-heated pig buildings and would never survive the sub-zero temperatures, so for now we're in the clear.
