Propaganda, is the glue holding society together.
The Truth, as in disclosure of the inner workings of large society, would not set people free, it would simply lead to the END of large societies. No one wants to live in the "reality" of the world, because the reality is an unnatural structure which deviates significantly from our natural "Dunbar's number" (The 200 person collective).
Once you exceed that number, status and hierarchy MUST take over, as individuals do not possess the processing power to know every person.
The Maintenance of Status and Hierarchy is ultimately achieved THROUGH, Propaganda.
The King is neither especially powerful, nor especially smart, his gold is not especially rare, his wives and daughters are not especially pretty.
The King is just a man.
It is the Narrative we succumb to which makes it all work.
And in education, we are programed into our "roles" as slaves to the system.
Freedom from this charade, is Not-necessarily-better.
And so we act out the play as a form of price discovery, akin to parallel processing.
The solution to 98% of mankind's current problems is of course, go 100% veggie, but unfortunately, there is the greater likelihood that the cuff slips, and civilization unravels before This-innovation prevails.
