"This planet has — or rather had — a problem, which was this: most of the people living on it were unhappy for pretty much of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movements of small green pieces of paper, which is odd because on the whole it wasn’t the small green pieces of paper that were unhappy."
- Douglas Adams

"We will bury you" - Nikita Khrushchev

As the twentieth century ended, it seemed we had permanently done away with Marxism as a viable option. Certainly Krushchev was wrong - capitalism triumphed over communism. As I've stated earlier I think the battle was really more between democracy and totalitarianism, and democracy rightfully won. In the twentieth century capitalism supported democracy, but now in the twenty-first century we have moved into the realm of supercapitalism (more on this later). Capitalism and democracy are no longer mutually supportive. So perhaps, we can go back and learn a little from Marx and from democratic socialism. Here's more on this point.
