You are right, I missed that point and your analogy is better. Nevertheless, I also think that it is unlikely that the educational content of the internet will devolve into a bandwidth hungry activity (anyone have insights on this?), which is the cited example. After all, the elite of the United States is still educated in classrooms, and the most data that can come out of that is a video stream. See, for example, oyc.yale.edu, which provides video of lectures (and even transcripts), problem sets, tests and other materials. I think that a bandwidth divide just promotes a luxury divide (something acceptable in capitalism) and does not make the divide larger by affecting other divides, such as education.
