Actually, in traditional agricultural societies, almost everyone is a farmer. There's a reason that the vast majority of people in the middle ages were serfs -- it took that many people to feed themselves plus everyone else. You can actually gauge how advanced a post-agricultural civilization is based on the percentage of the population that works in the agricultural sector. Most thresholds of technological advance (most notably, the industrial revolution) have allowed a smaller farmer class to feed an entire society.
