When Prussia invented the modern "public" education system, conscripting children at bayonette point on occasion, they had a well-designed plan to provide docile cannon fodder and factory hands for the State -- that was the assigned destiny of 94% of the kids. By a variety of techniques, they were conditioned to focus on topics assigned by agents of the state. Every hour, a trumpet sounded, announcing that the topic was no longer worthy of consideration, and it was time to think about something else.
Another 4.5% of the kids went into "talented and gifted" programs designed to form them into the higher-end servitors of The State -- doctors, lawyers, accountants, professors, preachers.
Finally, the 1.5%, the children of the current ruling elite, got traditional liberal educations, centered on reading the great books, writing about great thoughts, and trying to apply the insights of the ages to contemporary issues.
Today's janissaries, today's "T&G" kids, may indeed be the glue that holds the empire together. However, they are still slaves.
