With all due respect, I must disagree with your analysis, Mr. Rath. You've neglected to consider the placement of certain key elements, such as the Incan Sentinel or King Slime. These figures of the story only ever come near the climax of a chapter, the end point. In this way, they clearly demonstrate the notion of the "Great Man" hypothesis of history; this, of course, is a concept neatly mirrored in Scrooge himself. And how do these stories always end? In violence. Far from the Great Men of History coming together to shape it, they squabble over the boundaries of their greatness.
Far from Greek Tragedy, the story is closer to political satire, an argument that any man who would seek to ascend will surely come into conflict with those who do likewise; it suggests distrust of authority and hatred of the privileged. It's closer to an endorsement of anarchy. (Indeed, the existence of a 'bad ending' gained by collecting no money defeats the suggestion of Greek tragedy, with that form's implication of fate. This is about the economic jungle, and the invisible hand being red in tooth and claw.)
(I am so sorry for the mixed metaphor at the end there and any images produced thereby.)
