I think government involvement is what's holding prices at a stable level. I also think large operations must expand their production to keep a profit margin. Murphy Farms is a large hog operation near me. They have their own cutting and packing operation. Their hand is in it all the way to the consumer's store of choice. My friend is strictly a grain operation, corn/soy beans. He wants the government out of it. His operation is closely monitored and controlled by USDA. He has very little wiggle room of his crop ratios.
I don't know what the answers are either. I'm afraid we are spoiled by cheap food prices. Sure doesn't feel like it when you have $150 of groceries in one cart. But upon closer inspection, a lot of waste is discovered. Very large percentage of purchases are pre processed and packaged for quick use. That's expensive.
In regards to family operations, getting harder to define that.
