I'll start off and just say the biggest difference I've seen is in the economies of size, from where my father started out with a small hog operation that he could run himself to when my brother and I bought him out and we had people helping. We had four employees in the barn. It was 450 sows with 4,000 acres of land, and that was just to make a reasonable income in this day and age. In the sixties and seventies, he would have had the world's biggest farm.
That is making it extremely difficult for young farmers to get in.
I met with my accountant the other day and he said, you should be at 10,000 acres if you're only a grain farm. With economies of scale, you've got a 4,000-acre farm. You've got to start hustling; you've got to start growing if you want to make a good living.
