In depth exploration of the importance of class structure in Marxist literary criticism, it is pointed out that class structure is the foundation of class analysis, involving the division and position of social classes. Sociology has various descriptions of class structure, such as pyramid shaped, olive shaped, inverted T-shaped, etc., which can generally be divided into two categories: vertical hierarchy and parallel differences. Marx's binary opposition structure and Weber's parallel difference structure are the two main models of class analysis. In the mid-20th century, the rise of middle-class theory challenged traditional oppositional structures, but with the acceleration of globalization, the issue of binary class structures has once again received attention. Scholars such as Wright and Jameson have conducted more complex analyses of class structure within a new theoretical framework, emphasizing the subtle manifestations of class conflict in cultural and aesthetic fields. The article explores the relationship between class structure and cultural expression from a class perspective, including the binary opposition structure of the lower class perspective, the ternary structure of the middle class, and the vertical class structure of the upper class perspective. The author attempts to reveal the class relations behind cultural phenomena, go beyond simple class analysis methods, and gain a deeper understanding of the impact of class structure on people's perception of life, literary imagination, and emotional expression.

1、 Binary opposition structure and typicality as a metaphor

Deeply explored the importance of class structure and emotional expression in Marxist literary criticism. By analyzing Claude Levi Strauss' research on the organizational structure of primitive tribal societies, this study reveals how different members of society form different perceptions of social organizations based on their own class status. Levi Strauss' concepts of "diameter structure" and "centripetal structure" reflect different understandings of tribal composition among members of society, which echoes Marxist ideological theory that people's worldviews are influenced by their class status.

2、 The Triple Class Structure and the Universality of Middle Class Aesthetics

Sociologists typically use an olive shaped structure to describe the class structure of developed Western countries, with the middle class comprising the majority. However, this model is not applicable in the third world countries because they have a small middle class population. Marx believed that the middle class is a constantly diverging class that may rise to the bourgeoisie or fall to the proletariat. From the beginning of the 20th century to after World War II, the European and American economies prospered, and the middle class expanded rather than decreased. The structural functionalist class theory has received attention, and Marxists such as Wright Mills have also described the rise of the white-collar new middle class. The middle class, as the main social group, has become a focus of sociology. But there is a contradiction between the class structure of modern society and Marx's class theory, and the growth of the new middle class has become a challenge in the theoretical field.

3、 Vertical hierarchical structure and demonized East

Deeply explored the relationship between class structure and emotional expression, especially from the perspective of Marxist literary criticism. The article first analyzes the binary opposition structure of the lower class and the ternary structure of the middle class, as well as the aesthetic mechanism of the transformation from the ternary structure to the binary structure. Furthermore, the article supplemented the dimensions of class position and perspective, emphasizing the importance of the position of the upper class, the top-down perspective, and the consciousness of the ruling class.

4、 Conclusion

The paper explores the relationship between class structure and emotional expression, pointing out that binary structure leads to conflict, while ternary structure conceals opposition. Jameson analyzed the envy and hatred between classes through the concept of Libido, while Nietzsche despised resentment. The middle class pursues supra class taste, and its aesthetics are based on surplus value, which is reflected in various rhetorical forms of surplus value in late capitalism. The top class maintains unequal relationships through financial aesthetics, and the class position itself has financial attributes that can be transformed into sustained benefits. Through interdisciplinary analysis, the paper reveals the complexity of global class structure and emphasizes the importance of class analysis in understanding social reality and individual positions.
