Taking Unz's argument at face value, I think the article serves more to illustrate that members especially of the upper-middle class are disturbed by the gross lies that corporate media are spreading than it serves to argue for an effective strategy to counter their lies.
The capitalist system is based on private ownership of any productive enterprises in societies. Thus the owners inevitably evolve into a class with considerable power over the rest of society and over time, because of the dynamics of capitalism, ownership becomes concentrated in fewer and fewer hands. The security of the vast majority of people are faced with increasing wars and precarity, and they naturally engage in all sorts of resistance. To counter such resistance, the owner class must counter this resistance by using their media to spread ever greater deceptions about what they are doing in the world. This is precisely what is happening today.
The class that has contributed heavily to this end-development of capitalism is the well-rewarded upper-middle class of technologists, scientists, and highly
I noticed on the right side of this posting that he posted an interview with David Harvey, a noted American Marxist, conducted by Chris Hedges. Because David Harvey has not appeared on this website before, it seems to me that Harvey's post was juxtaposed with this article in order to establish his neutrality and credibility regarding capitalism. Considering the evidence of his postings as a whole, I think Unz, as a member of the upper-middle class and a conservative, is worried about the fascist direction that his masters in capitalist ruling class are going. Thus, he and his fellow-rebels are waking up and smelling the foul odors emanating from the increasing fascist actions taken by their masters in the capitalist class and they are defecting--but only so far. Not far enough to challenge the system from which they have benefited so much, but are only desperately striving to return to an earlier stage of capitalism like in the 20th century when they, as an upper-middle class, flourished.
However, there is another argument that one could make--I won't because I prefer to believe that Unz is honest--that he and agents of the ruling class are cleverly trying to co-opt alternative media to tame it and capture its audience as much as possible so that the threats posed by this opposition media are diminished.
