Bernie Sanders’ campaign has finally gone full-throat with the 
obvious: the Democrat-aligned corporate media have thrown all 
journalistic principles to the wind to impose a “Bernie Blackout.” 
How can someone who was the most popular politician in the nation  in 2017 be made into a non-person? It’s all intimately entwined with the multiple crises afflicting late stage capitalism.
In the absence of massive, grassroots movements, corporate voices 
always drown out all the others. Capitalist ownership of the media 
allows the rich to frame their own worldview as the political “center,” thus
 relegating contending ideologies to the “extremes” of left or right. In
 this sense, “centrism” is nothing more than the political position of 
the corporate owners, who construct media versions of reality that make 
corporate-concocted policies seem the most logical, commonsensical and 
socially responsible approach to the world’s problems. As long as the 
rich can sustain broad public trust in the “truth” of their 
“journalistic” products -- newspapers, electronic newscasts, books and 
other media created by professional operatives directly answerable to 
rich owners – widespread revolt against the corporate order is 
unlikely. 
Most people in all societies want to be perceived -- and to see 
themselves -- as sensible, responsible and knowledgeable. When polled on
 political questions, they are eager to give the “correct” 
(corporate-endorsed) answers. Only the most marginalized, alienated and 
systematically demonized sectors of society will consistently buck the 
corporate narrative. In the United States, the biggest historical 
resistance to the corporate (rich white man’s) worldview has come from 
Black America, a besieged people with a unique social perspective who 
were compelled to create their own media in desperate defense of their 
collective humanity. However, the demise of Jim Crow apartheid and 
subsequent absorption of many of the “best and brightest” Black minds 
into corporate service, has dulled Black defenses. After two generations
 without a mass, grassroots Black movement – a politically desolate 
period briefly interrupted by the “Black Lives Matter” mobilizations of 
2014-15 -- African Americans are also more likely to give the “correct” 
answers to corporate media surveys.
But not the youth of all races, who know that capitalism, as
 they experience it, promises them nothing but endless austerity and 
war. Majorities of young Americans now embrace a version of “socialism” 
that is actually merely a less vicious capitalism, made kinder by a 
comprehensive system of social supports – similar to the “social 
democratic” order in northwestern Europe. But late stage capitalism is 
relentlessly eviscerating the European model and has no intention of 
allowing a replica to be erected in the United Corporate States of 
America, the global headquarters and armory of the Lords of Capital.
