Marxism doesn't work.
Any college student with sense who reads enough world history will eventually reach this conclusion. Study for even a few minutes, and anyone can detect the rot at the core of Karl Marx's central thesis.
This presents a problem for the woke totalitarians of today. If anyone can find out that your core ideas are built on a fraudulent, evil system just by reading, then even the most sophisticated propaganda campaign will not be enough to win hearts and minds.
Their solution?
Begin the indoctrination process before people can read.
