 Class systems
Historically, class systems in many countries were rigid elitist hierarchies, such as the feudal system in Europe, and caste systems in many parts of Africa and Asia. Under these systems, people of the lower classes generally had relatively few civil rights and usually no hope of achieving greater wealth or status.
In modern capitalist societies, class is much less rigidly defined, and there are vastly greater opportunities for social mobility. For example, people from working class backgrounds may enter traditionally middle class jobs. Meanwhile, communist countries have endeavoured (theoretically, at least) to get rid of class systems altogether. Nevertheless, class divisions continue in both capitalist and communist societies.
 Class and politics
A lot of left-wing politics and analysis focuses heavily on class issues, especially since the writings of Karl Marx, who perceived classes to be bound by common economic interests and "class struggle" to be a defining factor throughout human history. Socialism ultimately aims to destroy the class system, and socialist movements appeal strongly to working class interests, and promote "class consciousness", as do trade unions. The hammer and sickle emblem of the Soviet Union represents the workers of both agriculture and industry.
However, there is also a strong tradition of working class conservatism, backing parties such as the Republicans, as demonstrated, for example, in the Joe the Plumber interlude during the 2008 U.S. Presidential Election campaigns. When workers support such parties, it raises a number of questions that intrigue the theorists of social class no end, viz.:
- Whether these parties truly serve the interests of their working class supporters. This remains a disputed issue, especially among left-wing critics of these movements, with workers voting and left-wingers stating that the workers are voting against their own interests.
- What exactly are the "interests of the working class." One will often get vastly different answers to that question from a worker and a theoretician; the latter often state that such interests consist of "empowerment," the adoption of "liberatory dialectics," etc., while the former may regard them as being "better wages and shorter working hours and nobody bossing you about" or dispute that the "working class" has any unique common interests at all.
- Assuming agreement on what the "interests of the working class" are, whether or not workers should consider factors such as other people when advancing such interests. The belief that they should is often termed "false consciousness." A common example is when workers consider that all people, including non-workers, have certain constitutional rights, such as the right not to be disseized without due process, which tends to slow down the pace at which the "interests of the working class" are advanced.
Far-right movements such as fascism and Nazism appealed strongly to working class communities at the time, and many Neo-Nazi and white supremacist subcultures continue to recruit working class supporters.
None of this should be surprising, however, given that working classes form the largest section ("the masses") in any society, and so can be a powerful political factor in societies with universal suffrage and mass media. Naturally there are movements from all sides of the political spectrum aimed at working class voters and supporters.
 Class and Culture
Although class is largely defined by occupation, education and income, the divisions are not purely economic: they are partly cultural too, with different lifestyles, interests, behaviours, dialects and subcultures being associated with different classes. These class differences have a marked impact on the spending habits, and thus are among the factors, along with age, gender and income, considered by corporations and advertisers when assessing their target markets.
This cultural aspect of class may be one reason why the class system is still perpetuated in societies where (theoretically at least) equal opportunities are available. Class divisions may also be perpetuated in part by attitudes and values within classes, such as peer pressure and the work ethic, which compel people to follow conventional expectations rather than seeking their own fortune.
 Class structure
There are any number of different theoretical models and schematics for defining or understanding social classes in modern societies, but most of them share some common features, being loosely divided into upper, middle and lower classes. A loose breakdown looks something like this:
 Upper class
The upper class is usually known as the "ruling class" in post-Marxist discourse. In pre-capitalist societies, the upper class was made up of hereditary aristocracy, but aristocrats are largely irrelevant or non-existent in modern societies. Marxist doctrine sees the upper classes as the "owners of the means of production"; in common, contemporary parlance, upper classes are made up of the wealthier segments of society, such as corporate executives and "fat cats", often from privileged backgrounds.
 Middle class
The middle class is more affluent than the working class, but less wealthy than the upper class. University education is common, and "white collar" jobs are most usual, though these cover a wide array of roles and incomes, including professional, clerical, academic, retail and service jobs.
The middle class and is often subdivided into an upper and lower subset. The upper middle class tend towards professions such as law or medicine, to bureaucratic positions, civil service, or middle management levels of administration. The lower middle class, or "petit bourgeoisie" as Marx would have it, include office workers, shopkeepers, salesmen and some skilled trades.
 Working class
Also known as the "proletariat", working class jobs include manual labour, such as mining or factory work, and many routine clerical and service jobs. These "blue collar" jobs usually require a lower level of formal education than "white collar" work, though many skilled trades, requiring years of training, are traditionally working class, such as carpentry and metalwork.
As with the middle class, class models often subdivide the working class, or include an additional "underclass" (i.e. the poor) made up of those who barely participate in the economic sphere: the unemployed, those reliant on benefits, and unskilled labourers without a steady source of income.
 People in rags
Karl Marx also described a fourth class of people, the lumpenproletariat or "rag workers." He held that these people were just as badly under the thumb of the upper classes as the proletariat were, but were
Lebensunwertes Leben useless in class struggle, owing to their dependence on alms from the upper classes. The lumpenproletariat included "swindlers, confidence tricksters, brothel-keepers, rag-and-bone merchants, beggars, and other flotsam of society."
