2. Class is the product of the development of social production to a certain stage, that is, the insufficient development of production. There are two basic prerequisites for the emergence of class: first, the emergence of surplus products; The second is the formation of private ownership. The essence of class is a social group or a community of people with different economic status, which is related to specific production relations. The division of classes is determined by people's different positions and relationships in a specific social and economic structure.
3. The English word for "class" is "class". In different times, different countries and different discussants have different understandings of its meaning. Lenin once defined "class" like this: "The so-called class is such a large group. These groups have different positions in a certain social production system in history, different relations with the means of production (mostly stipulated by law), and different roles in social labor organizations, so the ways and amounts of obtaining their own social wealth are also different.
4, the so-called class, is that some groups, because of their different status in a certain social and economic structure, one of them can occupy the labor of another group. Here, Lenin's concept of class has such a feature. It is first of all a "group", which is associated with "social labor". It has no individual characteristics.
