In the human society, everyone is supposed to be of use to somebody. Farmers grow crops which is of use to every living human being, bakers bake, bus drivers take people from A to B, painters paint, manufacturing units churn out 'things' that is used by a lot of people, software makers build software that is used by industries and users to improve efficiencies and so on. All of these skills are crafts that different kinds of people excel in to different degrees. Everyone is a consumer of a product or a service made by creators (almost everyone). Everyone is a consumer and a creator to some degree.
