It is frequently assumed that the mechanization of work has a revolutionary
effect on the lives of the people who operate the new machines and on the society into
which the machines have been introduced. For example, it has been suggested that the
employment of women in industry took them out of the household, their traditional
sphere, and fundamentally altered their position in society. In the nineteenth century,

low levels of skill and offer women little opportunity for advancement all persist,
