"Tradition".
Also consider public schooling (in the US) didn't really exist until about 1920 and wasn't widespread until the 1950s. Prior to that you learned to read from the Bible. It was the only book you could get cheap. Half the country was fucking farmers and homesteaders during the 1800s, they didn't know jack shit. Newspapers were published a month before you got them, assuming you had even access to a town that sold them.
We're like 5 generations or less away from semi-literate morons that could barely do addition. They relied on a magic book to give them hope as their children died from cholera, measles, whooping cough, and 17 other deadly diseases from a century ago. Life fucking sucked any time 100+ years ago. It was a fucking nightmare don't let these "return to tradition" fuckwits tell you different. When the Amish go on "Rumspringa" (teenage vacation from their village) half of them don't come back.
Of course you need religion when your world is fucked. Look at Africa. Like 97% rate of religious worship and it's worse than the US in the 19th century.
