MCU: 10 Real World Issues Addressed In Marvel Films
10. Captain America The First Avenger: Disenfranchisement
Despite being your average war-era Nazi punch-em-up, Captain America's origin story does a great job outlining what actually made Steve Rogers special: his humanity as a disabled, poor young man was never lost even when he became heroically huge.
The Nazism was a pretty obvious story point, but it was never quite as focused on as Steve Rogers's story about a disabled kid who was banned from fighting in the war, and his unrelenting determination to do what he could - not for glory or the need to battle, but to simply help others.
There's also the effective narrative of Peggy Carter, who, in a time of great sexism, which is expanded in her spinoff TV series, is able to save the world more than a few times in the years that follow.
The idea that these people, who were traditionally seen as weak and lesser, were the ones who could truly save the world, was one that this film impressed upon. Especially given that the ones wielding and preaching the value of strength and power were, in fact, the bad guys.
