The leader need not continue to spout socialist claptrap, except to continue to fool his flock. And they are willing fools. Given the socialist framework, the flock will fill in the blanks themselves, centralizing power in the center. All to the advantage of the boss, who doesn't give a damn about the flock.
That's why we still hear communist dupes who tell us socialism failed in the Soviet Union because it wasn't done properly. The leaders didn't quite get it right. Not so. Socialism failed in the Soviet Union because socialism does not exist.
So, what can we say about the United States today? Our leader, and those who are his helpmates, do appear to be committed socialists. That means they haven't looked behind the curtain. They don't know the magician's trick.
