every person that has a college degree either takes micro or macro economics and in these classes you learn about Keynesian economics v. Classical economics....
Even I remember this, and I graduated in engineering...
So the news media, especially the ones that are in to money, will know these competing ideologies...
Most people end up graduating thinking Keynesian economics is the best because the universities and texts push the phrase and justification of "in the long run we are all dead" slogan that supposedly justifies Keynesian..
