a discredited creed

Those words, in themselves, are revealing. They situate the question in the field of belief and ideology. Who has decided that the "creed" is "discredited" (meaning, no one believes in it any more)?

And what is the creed that the writer is implying everyone believes in now? What makes them believe in the new creed? The non-stop repetition of the mantra by high priests like the Economist?
