NPR marginalizes socialist perspective

NPR marginalizes Bernie Sanders and " socialism "   Just a few days ago I read that NPR was trying to marginalize the " socialist ", Senator Bernie Sanders of Vermont. The above article does not even suggest that there might be a very different SOCIALIST perspective on this capitalist society's many evils. Many intelligent, educated, articulate democratic Socialists have written at length about the root cause of all this social insanity. The Democrats and Republicans have only egocentric solutions: ELECT ME PRESIDENT.
None of these candidates will drop a hint that there is something very wrong with the capitalist system. Nor will most bought- and- sold radio, TV, and newspaper editors.
For a different perspective readers might check out the WATCHING AMERICA web site ( not " socialist " )
