Hustling is not new, only that its status has been elevated by economic realities. Even among our traditional societies, hustling existed. There have always been some members of the society at its periphery.
Most communities had chiefs and families at the top. Below that were other members of the society, the hustlers. Some societies had traders as the middle class but in most cases the middle class did not exist; you were either in upper class or lower class - a hustler.
