If anyone is interested in what our compulsory public school system is about I suggest looking into John Taylor Gatto, he was blowing the whistle on the school system in the 90s and he knew the whole history of where it turned into indoctrination camps and the methods they use in modern schooling.
John D. Rockefeller played a huge role in changing our education system in the early 1900s from a classical education (teaching people how to think) to the Prussian education system (teaching people what to think/indoctrination)
