Cynthia Selfe: "From our perspective today, of course, we can see a darker side of this dynamic. The economic engine of technology must be fueled by-and produce-not only a continuing supply of individuals who are highly literate in terms of technological knowledge, but also an ongoing supply of individuals who fail to acquire technological literacy, those who are termed 'illiterate' according to the official definition. These latter individuals provide the unskilled, low-paid labor necessary to sustain the system we have described-their work generates the surplus labor that must be continually re-invested in capital projects to produce more sophisticated technologies."
