The difference with a dream, as articulated by Martin Luther King, is that you strive towards it. You live within an illusion. And that illusion of who we are, where we're going and what we can become is... there's a wider and wider gap between that and the reality. And the problem with living within illusions is that it allows you to perpetuate a kind of eternal infantilism... childishness, where reality is never an impediment to what I want. But as the walls break down, when it's your house that is foreclosed, when your job and your neighbor's job are not coming back, when you go bankrupt for your medical bills, then you react as a child. Which is to call for a savior, a demagogue, someone who promises moral renewal, vengeance and new glory. And we are already seeing these proto-fascist movements leaping up around the fringes of American society. And this is because our empire is imploding. It, itself, is an illusion,. If we don't face that illusion, we're finished.
