Sanders gets so much flak from corporate media because his campaign
is upsetting the dominant apple cart. He relentlessly exposes a basic
contradiction: A society ruled by an oligarchy—defined as “a government
in which a small group exercises control especially for corrupt and
selfish purposes”—can’t really be a democracy.
The super-wealthy individuals and huge corporations that own the
biggest U.S. media outlets don’t want actual democracy. It would curb
their profits and their power.
