Upper, middle or lower class ?

Most of us at our HS are part of the middle to upper class. Some may be lower class but why does that matter? That doesn't change who you are. People always talk about how upper class people are smarter but in reality, it's not always that they are smarter, but that they have the money to get help when they need it, etc. People in the lower class can be just as smart but they actually try to get there, whereas upper class might buy their way into education. People may say there are certain "ways" to each class, but we are all the same. Money shouldn't determine who we are or who we aren't.
