When a single individual or family lived on farms and were largely responsible for most of their own needs, there was little need for intermediaries. Sheep provided wool which was spun into thread and woven into fabric. Local woods provided raw materials for furniture and even houses. With the rise of mechanization, however, it became possible for larger and larger quantities of raw material to be harvested¨cotton, for example¨that was then sent to a different location to be processed and then to another location to be made into clothing which was then sold through stores back to the people who might have originally harvested the cotton.
