How was fitzgerald a spokesperson for his generation? can you compare him with any celebrity today who is a spokesperson for his/her generation?

He was a spokesperson of his generation because his books mostly spoke about people who experienced suffering due to the gilded age system of values. This is seen in the Great Gatsby with Gatsby himself being a victim of society. Similarly to him a spokesperson for the generation today would be someone who fought against things that plague this generation like the climate change or the negative effect that the technology has had on people.
