In the interest of answering the conspiracy theorist OP's question, I thought immediately of Philip Short's biography of Pol Pot and its reference to the cpap, collections of traditional sayings taught to Cambodian children:

The cpap, at least in the form in which Sār [the future Pol Pot] would have learnt them, had another particularity. They portrayed the Khmers [Cambodians] as honest and sincere but "foolish and ignorant", constantly being duped by their smarter Chinese and Vietnamese neighbours:

Your eyes are open and can see,
But see only the surface of things
Learn arithmetic with all your energy
Lest the Chinese and Vietnamese cheat you
The Khmers are lacking in judgement
They eat without giving thought for what is proper and right,
Each season they borrow from the Chinese,
And the Chinese gain control of the inheritance their parents have bequeathed.
(To clarify, I don't believe the Chinese and Vietnamese are evil! But from a historic Cambodian point of view they are definitely the designated villains.)
