One of my biggest takeaway from the 20th century study of history has been a wariness of using the words "Golden Age" or "Dark Age" alone to draw conclusions about what life was like for people outside of the elite.
As such I'm don't think the presence of a Golden Age is itself a particularly strong argument for literacy among the general populace.
