Indoctrination happens through many channels—entertainment, speeches, and censorship––but its main instrument is the school system. Teachers have a captive audience of malleable young minds for several years. They may not have figured out how to make students smart and productive, but they can at least make them submissive and obedient.
Judging by results and from most people’s experience, indoctrination is not only a problem with rogue regimes, but also a distinctly American problem. However, here it is difficult to determine the extent of indoctrination, how it works, or even if it does work.
