Some conspiracy theorists are convinced that schools, universities and other state or private educational institutions serve as tools for the elites to establish the New World Order (NWO). This is why children and young people literally only learn bullshit there. In reality, the conspiracy theorists believe, the schools would serve as propaganda and conditioning centres: their sole purpose is to brainwash the population from an early age (and therefore particularly sustainable) so that they later support the agenda of the elites.
However, this far fetched theory does not reveal any hidden truth about the education system, but rather reveals the twisted world- view and paranoia of many conspiracy theorists.
