Literacy and Orality

In her article, Heath explains that Trackton does not place a high value of print literacy in the home, and that adults “do not buy books for [their children]” and they “do not create reading and writing tasks for the young” either.  She further explains that “to read alone was found upon, and individuals who did so were accused of being antisocial”.  In this way it seems that literacy and orality in Trackton are completely intertwined and linked.  Do you think that this is why in societies that are not saturated with literacy in the home orality is so prevalent and the desire to master print literacy is lacking? Is it in societies such as these that the lines of literacy and orality are almost completely blurred? What would need to occur that would transition a society such as this one into one that values print literacy in the home?
