It took a long time and effort to get people to accept these ideas as gospel, and it took a lot of time and effort for people in 1930s Germany to accept that Jews are sub-human creatures which need to be destroyed fro Germany to prosper. This book shows this process a little bit in the latter case. There are many works which do a similar service for the contemporary version– John Kenneth Galbraith, Erich Fromm, C. Wright Mills, Noam Chomsky, Naomi Klein are all writers who have dedicated a large or sizable part of their career about showing the way our society actually works. Adam Curtis of the BBC has been making documentaries for decades which show among many other things the way public opinion is created and molded, such as The Century of the Self, a film I highly recommend to everyone.
Hitler and the National Socialist Party very deliberately and conscientiously showered the minds of Germans with propaganda about the supremacy of the German race, the need to bury one’s individualism for the sake of goals held in common by the nation, and the inferiority and evil of Commies, Jews, Gypsies, Slavs, etc. The propaganda was self-contradictory and incoherent upon anything past a cursory examination, yet it was no less effective for that. Once the ideas of the Nazis became accepted as the norm, common, average Germans could be gotten to perform tasks in direct conflict with more basic forms of morality, things such as shooting unarmed women and children.
