Neither am I. Farmer's aren't as diverse now. There are far, far more row crop only guys out there and you're hardly diversified in terms of farming if you simply put up a building and take no ownership of the lives inside. You're a hired man who took on the largest cost of the operation.
I think many are still diversified, it just looks different today than it did 40 years ago. Livestock used to be the way to diversify, but today you have diversification through full-time non-farm jobs, trucking, tiling, excavating, manure pumping, selling seed/chem, selling crop insurance, custom spray foam business, custom farming, rental houses/apartments, and in addition to that some operations did keep livestock around.
All the enterprises listed above are first-hand examples of farmers diversifying their operations and keeping their labor busy year-round. The only one's that are crop-only guys here either have a ton of acres or have a paid-for land base.
