What is the theme in Rocket to the Moon by Clifford Odets?

One of the novel's main themes is the Great Depression. While Rocket to the Moon may be less explicitly political than Odets's earlier plays, the effects of the economic pressures brought about by the Great Depression and the increasingly consumer-oriented nature of the American economy are central to the play. The influence of the Great Depression on the characters in the play can be seen most clearly in Cooper. A veteran of World War I, Cooper struggles to make ends meet because his dental practice is failing, and the economic demands of supporting a family exceed his income.
