Certain groups indeed seem to work under compulsion. Others work in order to keep property or get rations from the state. Still other laborers were free men and women for whom social mobility was a possibility. Many families travelled together in search of labor. Such laborers could amass private property and even be promoted to higher positions. This is quite a different picture of a laborer's life than the previous belief that they were afforded no way to move out of the social group they were born into.
