nostalgia and authenticity have become important drivers of social processes.
This is very relevant to American culture today. It manifests itself through food, fashion, facial hair, etc. For example, it has only recently become "cool" to have outrageous mustaches and big scruffy beards. Am I jealous because the only impressive facial hair I can grow is a neck beard? Yes. But that is beside the point. The hipster movement is sweeping across America and across many parts of the world. However, this doesn't mean this movement is totally authentic. A lot of new coffee shops that appear gourmet and use french presses are really just Starbucks that make you wait longer for coffee that doesn't taste appreciably better.
