Two thoughts: pg says we are designed but then in the notes he says "by evolution." Since evolution is changing to fit and survive your environment, perhaps humans working in groups is better for their survival. Also, specialization of labor has created this concept. Humans used to provide their own food, shelter and transportation that's all they needed to do. But when one person specializes in transportation, one in farming or hunting, and one in building shelters things start to change. And we end up with companies that only build pipe fittings.
