Travis served in the United States Corps during the Vietnam War. He was controlled by rule and experienced killing people in the war. This experience made him more suffer to live in society even more in his job, a taxi driver. In the beginning of the movie “taxi driver”, Travis Bickle says “Someday a rain will come and wipe this scum off the street”. A job of taxi driver has no choice but to see the dark side of society. And he was tried to keep his temper all the time, when he saw crimes, prostitution, etc. It was most bothering thing to him, because he was a taxi driver. It means that he does not have any power to distinguish between right and wrong or make them correct. He just endured. This gap between his though and act made him to be suffer from insomnia.

Furthermore, Travis is a symbol of people who live in New York City. People who live in the city are agree that modern products have improved the quality of our lives but they feel lonely between people and feel of alienation from human society. These city people’s lonely and sense of alienation portrayed as the taxi driver. Travis came in contract with many people, but they became strangers after they arrived at their destination. He could drive anywhere in NYC, but it was just outside of the city. He did not connect with other people. His suffer would be represented by his saying, when he catch a holdup man. He said “A man takes a job, you know and that job becomes what he is.” Therefore, a lonely and isolated taxi driver became himself. Also, when we ask about who is he/she; we answered his/her job rather than description of him/her. This is well represented of 1970’s society.
