This is probably the best thing Greenwald has ever written. Everyone in (or interested in) media, politics, government, academia, etc. should read it carefully and with a wide open mind. Grappling with this piece, its linked pieces, and Twilight of the Elites should be something that is now done in earnest; this is a chance for elites in other troubled western countries to work on getting ahead of the problem, as they failed to do previously, before it really gets out of hand.
The status quo is a failure, and continued denial will only lead us down an ever-darker road. We need a new way.
