Well its simple really, you're putting thought and processes into the Nolan films that aren't there. You give an example and then immediately parallel it to something in your own life. The connections back to the film are loose at best and for some of them barely parallel.
You could do that with any film, the idea of Captain America being a man lost in time and seeing how technology has not only pushed the boundaries of education but completely juxtaposed the ideals of what humanity should/would be in the 1940s, the idea of Tony Stark attempting to redeem his past sins of war mongering by using the same technology to fight a shadow of his former self. The idea of Thor being a god amongst men, in love with a mortal and dealing with the realities of how fragile humanity really is when depowered and how sacred one sees the bloodlines of family when Loki finds out he isn't "pure". Black Widow being a woman in a male dominated industry. The Hulk is dripping with modern day overtones dating back to Frankenstein's monster and Dr. Jekyll and Mr. Hyde not only that but given that this film universe's Hulk deals with Banner looking for cures for common diseases destroying humanity, it begs the question how far is too far for Science and at what point does it turn us into raging monsters?
I could repeat the parallels for Transformers, Back to the Future, Men In Black, Clerks, whatever I wanted to if I saw fit.
You can put any slant into things that you want, you are simply choosing not to with Marvel films and waaaay overloading into Nolan's films.
None of those things are there, you put them there. If it helps you enjoy the films fine and if it makes you a better fan fine but it doesn't mean the rest are in any lesser or even different category simply because you chose to not include them as catalysts for your own thought processes.
