How does Harry alienate other people?

In context, Harry alienates other people. He looks down on those he feels are not up to his level (this includes entire groups such as Hispanics or farmers, but also individuals such as Charlie Stavros). He is unduly in awe of those he considers his equals or superiors, for example, Webb Murkett. Harry sets great store by what he takes to be Murkett's astute investment savvy, buying then selling gold on the strength of casual comments by Murkett.
