Abstract: "Return to class" is a response and counterattack to "class extinction".The theory of "return to class" maintains that social class structure and class relations have indeed changed in history,but the essence of class and class relations have not changed;class continues to exist and affect society,and class analysis is still an effective tool to analyze the society.The effort of "return to class" is attributed to the contemporary labor research that regards workplace as the place of power system and class confrontation,which correctly reveals social class inequality from the perspective of "workshop power".The reappearance of class discourse is the theoretical echo of social inequality.In the new era,the existence of class shows the new characteristics and trend such as the "new poverty" of the working class,the "proletarianization" of the middle class and the formation of global industrial class.We should return to class,bring workers back to the center of analysis and adhere to and reshape class discourse from a new perspective.

Key words: class extinction, return to class, class inequality, economic globalization, worker politics
