In what ways is the study of cultural texts a benefit?

Studying cultural texts is beneficial because we get to learn how our culture differs from the others to better understand them. For example, in the short story "Red Convertible"  a veteran on an Indian reserve is unable to get help with his PTSD and resorts to committing suicide. It's beneficial that we learned about this because we are used to a lot of help with mental health in school and in the media in our culture. However, in the short story we see that living on an Indian reserve people don't have nearly as much access to help with mental health. Therefor, after reading the short story and seeing how our culture differs from theirs we can better understand their culture.
