Obama won't talk about single-payer health insurance. He won't talk about doing away with the Federal Reserve System either. He can't. The plutocrats won't let him.
He can't talk about the inherent conflict between democracy and capitalism. Democracy is the next biggest enemy of capitalism — next to Christianity. Christianity and then democracy are much bigger enemies of capitalism than was coercive socialism in the form of Marxism.
Could Obama "betray" the plutocrats rather than the people? Not and live he couldn't.
