Destination: Earth

• Overt: The United States has the highest standard of living because it has oil and competition.
• Covert: Communists are backwards and have a lower standard of living because they don't have oil and aren't capitalist. America's better than them and Americans should support our oil-run capitalist society. If you don't, you're a communist.
• I know that's the overt message because the video outright states that and the oppressed Martians eagerly begin changing their society to match America's.
• I know that's the covert message because it's glaringly obvious that the oil companies who supported the cartoon want people to like the oil industry because it helps America be America. The Martians are also obviously meant to be communists.
