This is only true for a segment of the public. The dummies who are drawn to a belligerent, enfant terrible like Trump are certainly BEING deceived. They also have no problem with the way Trump speaks down to Black people, wants a wall against Hispanic immigrants, and thinks all the world's problems are the fault of Muslims... rather than the U.S./NATO wars of aggression that catalyzed violence spreading out from the bludgeoned Middle East.
When you consider the Bell Graph, you recognize that there will always be a percentage of VERY awakened persons, those who are endlessly curious about the makings and workings of their world. And there will always be a percentage easily led due largely to their upbringing in authoritarian, typically religious fundamentalist households. And this group is easy to draw along into any disastrous, frequently pro-war policy.
There's also the large middle zone. That group can be educated if given truthful information. And that's the group that the Zinn quote most refers to.
I've spoken about the contaminated media for YEARS in this forum and that serious issue is always clouded over by those who blame the people who have BEEN deceived. Their anger is at the persons who don't understand they're being lied to rather than those DOING THE LYING.
And as I've pointed out, proponents of the "blame the people" frame identify WITH the dominators; and those dominators come from 3 major groups:
- Military muscular power
- Corporations with financial power
- Fundamentalist (or otherwise Conservative/Patriarchal) religious institutions
When those 3 share an agenda (which is now largely the case), the public will be lied to (it's called propaganda and it's become a major industry), and on the basis of that deception, can be made to go along with horrors.
The Goering quote is what it all comes down to; and it was hardly lost on those military elites and NSA spooks who imported Nazis into the U.S. Armed Forces labyrinth.
Zinn explains (in this excellent link) how human nature works when massive lies become the intellectual currency of the land.
Note the extent to which today's inconvenient Truth tellers are being prosecuted or forced to live in exile. Essentially, this cuts off any alternative story to that pushed as the official state narrative.
In many ways the protocols resemble a covert Inquisition.
