1 1. Cultural customs

Early immigrants brought European culture to America. Soon, these cultures spread all over America. Today, the United States has become one of the mainstream of world culture. Many American artists have made great contributions to the development of new styles, new ways of self-expression and even new cultural models.

The main content of American culture is to emphasize personal value, pursue democracy and freedom, advocate pioneering and competition, and stress rationality and practicality. Its core is individualism: the supremacy of the individual, the supremacy of selfish desires, the pursuit of personal interests and personal enjoyment, and the ultimate realization of personal value through personal struggle and personal self-design. This individualism, which deliberately shapes itself and pursues individuality, has both positive and negative aspects. It mobilizes the enthusiasm of individuals and enables many people to give full play to their wisdom and potential, thus promoting the rejuvenation and development of the whole nation and country. But if everyone takes me as the center, it will be difficult for interpersonal relationships to be harmonious and the whole society will lack cohesion.
