Answer (2)
Problem:Class Conflict: The story highlights the disparity between the taxi driver (representing the working class) and the wealthy passengers he encounters. The driver feels a sense of frustration and helplessness due to the social and economic divide between him and his affluent passengers.Moral Dilemma: The taxi driver struggles with his feelings of resentment toward the wealthy and his desire for dignity and respect. He experiences an internal conflict between his need to earn a living and his disdain for the way his wealthy passengers treat him.Solution:The solution in the story is not straightforward but rather involves the taxi driver’s self-reflection and personal growth. Through his experiences with various passengers, he learns to navigate his feelings of resentment and frustration. By the end of the story, he begins to accept his circumstances and finds a sense of dignity in his work as a taxi driver, recognizing that his worth is not defined by his passengers' wealth.
