The wealthy for millenia have known the "uneducated" are easily manipulated to work for nothing to stay alive. Kings, monarchs, most "religions" know that their wealth grows when they control through fear & punishment. Being unable to read or question why an "owner/god" is punishing them allows the "owner/god" to keep them under their iron fist. Education is the beginning of freedom. the "existance" of "hell" alone has reaped much gold.
