The system of education that we use in the United States (and many other nations) is called the Prussian Model. Born of Prussia’s military failings in the Napoleonic Wars, the German kingdom developed an “education” system designed to indoctrinate children, year-by-year, from age 6 to 16, into full compliance with the state and its military leaders. The point was, bluntly, to ensure that “no German soldier would ever disobey an order again.”
