the upper class individual stays with the upper class group because they are comfortable in their own groups. Therefore, it cause difficulty for the upper class individuals to connect with the lower individuals because they do not have their subcultures in common. However, according to the article, there is still a possibility for connections between two classes.
I like the idea that if people between classes can connect with each other more easily, then their self-identification of being upper or lower class grow weaker. I like this idea because it is true for many people, especially students on college where the diversity between these two classes abounds. After all, we are humans that always need each other. I think this is a better picture of differences between the upper class and lower class family.
