Interpreting Kafka

Kafka's The Metamorphosis is considered by some to describe the human condition in the modern world. Focusing on Gregor and his life, what would you consider to be particularly modern? Name two or three things. (Keep in mind that the book was published in 1915; "modern" thus refers to the early 20th century, not the present day. Think: Modernism and its concerns!). Then in a paragraph or two, explain why you think Kafka chose to turn Gregor into the insect instead of another member of his family. In other words, what did Gregor as an insect represent?
