The class system is universal phenomenon denoting a category or group of persons having a definite status in society which permanently determines their relation to other groups. The social classes are de facto groups (not legally or religiously defined and sanctioned) they are relatively open not closed. Their basis is indisputably economic but they are more than economic groups. They are characteristic groups of the industrial societies which have developed since 17th century. The relative importance and definition of membership in a particular class differs greatly over time and between societies, particularly in societies that have a legal differentiation of groups of people by birth or occupation. In the well-known example of socioeconomic class, many scholars view societies as stratifying into a hierarchical system based on occupation,economic status, wealth, or income.
According to Ogburn and Nimkoff a social class is the aggregate of persons having essentially the same social status in a given society. Marx defined class in terms of the extent to which an individual or social group has control over the means of production.In Marxist terms a class is a group of people defined by their relationship to the means of production.
Classes are seen to have their origin in the division of the social product into a necessary product and a surplus product. Marxists explain history in terms of a war of classes between those who control production and those who actually produce the goods or services in society (and also developments in technology and the like). In the Marxist view of capitalism this is a conflict between capitalists (bourgeoisie) and wage workers (proletariat). Class antagonism is rooted in the situation that control over social production necessarily entails control over the class which produces goods -- in capitalism this is the exploitation of workers by the bourgeoisie. Marx saw class categories as defined by continuing historical processes.
Classes, in Marxism, are not static entities, but are regenerated daily through the productive process. Marxism views classes as human social relationships which change over time, with historical commonality created through shared productive processes. A 17th-century farm labourer who worked for day wages shares a similar relationship to production as an average office worker of the 21st century. In this example it is the shared structure of wage labour that makes both of these individuals "working class."Maclver and Page defines social class as any portion of the community marked off from the rest by social status.Max Weber suggest that social classes are aggregates of individuals who have the same opportunities of acquiring goods, the same exhibited standard of living. He formulated a three component theory of stratification with social, status and party classes (or politics) as conceptually distinct elements.
According to Weber a more complex division of labour made the class more heterogeneous.In contrast to simple income--property hierarchies, and to structural class schemes like Weber's or Marx's, there are theories of class based on other distinctions, such as culture or educational attainment. At times, social class can be related to elitism and those in the higher class are usually known as the "social elite".For example, Bourdieu seems to have a notion of high and low classes comparable to that of Marxism, insofar as their conditions are defined by different habitus, which is in turn defined by different objectively classifiable conditions of existence. In fact, one of the principal distinctions Bourdieu makes is a distinction between bourgeoisie taste and the working class taste.Social class is a segment of society with all the members of all ages and both the sexes who share the same general status.Maclver says whenever social intercourse is limited by the consideration of social status by distinctions between higher and lower there exists a social class.
