Well, even to look at general public levels of education, virtually all adult Americans are literate; literacy was almost unheard of back in ancient times. Virtually all aduly Americans can do simple mathematics - something also almost unheard of in ancient times. I could go on, but the standard for education is much higher. People's "learning" in ancient times tended to have to do with farming, herding, gathering, fishing, pottery, carpentry, etc.
