Captain America - First Avenger -- and he wasn't well funded and really struggled. Hardly rich. In fact they treated him as a prop. He's bullied through the first thirty minutes of the film.

At the start of his film. And by the end, he's not in that position.

Iron Man -- he's captured by terrorists.

At the start. But it's not a film about Tony Stark having to deal with the fact that he's regularly kidnapped by terrorists, and being a superhero while regularly struggling with his weekly kidnappings... It's something that happened to him – not his life that happens.



I'm not sure you understand what I'm trying to say. I'm not saying these characters don't struggle. I'm saying that they don't have to fight for a balance between superheroing and their daily lives. (Batman, for instance, is constantly trying to be Bruce Wayne and Batman, and having each one of those lives affect the other one.)



ETA:

You really have to look at all the movies together as a whole.

Which... is also something I dislike about the MCU. They should work as a whole, but that shouldn't be at the expense of the standalone films.
