You're just repeating the obvious part of what he said; I already know this, I'm interested in the details of what differed between what the movies told them vs their actual experiences.
Just imagine you know nothing about the US except what you see in movies. Do you see a lot of poor people?
There obviously are movies and TV which show a much more "real" version of the world. But the most popular TV and movies tend to show an idealized version of reality.
I can't imagine that because I was raised here, that's why I'm asking. I saw plenty of poor people in real life and in popular movies; when I see American movies, it looks like home to me, it's where I grew up.
