Destination Earth (1956)
This animated cartoon follows the adventures of "Colonel Cosmic," a Martian, as he learns that Oil and Competition are the two things that make America great. It is a sci-fi-influenced economic tract on the strengths of Earth-style free enterprise economics, compared to a stagnating Mars under the fist of a certain Mr. Ogg, who centrally controls the Martian economy.
The evidence of Earth's prosperity is shown in petro-centric terms, narrated by the space traveler. This is subversive stuff for the Martians, and Mr. Ogg tries to control the spread of this information. Propaganda at its finest.
