I never even suggested that people couldn't be read to....I said that the VAST majority of the population could not read.
You poor thing ... in what epoch are you bogged down, the dark ages or the Time of Jesus, when people not only spole three languages in the region but read at least two of them in order to engage in commerce. Writing was so common in the Time of Jesus that there were little wax tablets all over the market places and in public forums. Statuary had inscriptions written on their pedestals, which people recognize immediately!
