Why does not Wilhelm like the city life?

In urban circumstances the rites of love or communion are enormously difficult. In the urban world of New York Tommy is considered to talk to him because there is no one else to talk to among the millions of a city like New York. There every other man speaks a language entirely his own and is an end in himself. Looking outside of himself and his small circle, Wilhelm feels alienated from humanity, as represented by New York City and its inhabitants. 

He feels that communication with others is as difficult as learning another language. Every other man spoke a language entirely his own. You had to translate and translate, explain and explain, back and forth, and it was the punishment of hell itself not to understand or be understood. Wilhelm has an encompassing sense that the alienation he feels is not unique to him, but that “everybody is outcast”. 

Tommy’s experience of loneliness is a part of the human condition in a post war society. The theme of ignominious isolation is established in the first several pages of the novel when Tommy stops to get his morning newspaper from Rubin. Both of them pretend that they are intimate in their talking, but neither of them talks about important issues. Their issues involve only trivial matters such as the weather, Tommy’s clothes, gin game etc. Though both men knew many intimate details of each other's personal lives neither of them talks about it.
