And Prussia lead the world, in many ways still do, teaching the children to be able to think for themselves so enabling them to educate themselves further, nowadays, just as the Clash sang, "white kids go to school, where they teach you to, how be thick", education is more about learning what "they" want you to think.
From Wilkipedia:-
During the 18th century, the Kingdom of Prussia was among the first countries in the world to introduce tax-funded and generally compulsory primary education, comprising an eight-year course of primary education, called Volksschule. It provided not only the skills needed in an early industrialized world (reading, writing and arithmetic), but also a strict education in ethics, duty, discipline and obedience. Affluent children often went on to attend preparatory private schools for an additional four years, but the general population had virtually no access to secondary education.
Emulation of the Prussian education system in the United States
American educators were fascinated by German educational trends. In 1818, John Griscom gave a favorable report of Prussian education. English translations were made of French philosopher Victor Cousin's work, "Report on the State of Public Education in Prussia." Calvin E. Stowe, Henry Barnard, Horace Mann, George Bancroft and Joseph Cogswell all had a vigorous interest in German education. In 1843, Mann traveled to Germany to investigate how the educational process worked. Upon his return to the United States, he lobbied heavily to have the "Prussian model" adopted.
Mann convinced his fellow modernizers, especially those in the Whig Party to legislate tax-supported elementary public education in their states. Indeed, most northern states adopted one version or another of the system he established in Massachusetts, especially the program for "normal schools" to train professional teachers[2]. In 1852, Mann was instrumental in the decision to adopt the Prussian education system in Massachusetts. Soon New York state set up the same method in 12 different schools on a trial basis.
