" This necessitated each village be self-supporting and self-sustaining. And, if you looked at 1100’s Europe, you would see that the types of jobs and professions the villagers took on reflected this fact. You had the butcher, the farmer, the blacksmith, the clothier, the knight, the baker, the goldsmith and of course the all-important grog maker. Everybody had a job or a task that carried their weight in the village. What you did NOT have was the professional activist, the social worker, the starving artist, the trophy wife, the socialite or the village welfare bum. Everybody had a job and everybody’s job provided vital and required services and products to the village. Now, the reason we understand this is because a village is a small enough entity for us to wrap our brains around. We see the little village with the little cows and the village people walking in the muddy streets. But ask yourself this question: How is a country any different than a village? "
