An achievement-based economic system with social mobility and relations between classes is known as an open class system.
By contrast, people in a closed class system have been confined to their ancestral occupations, and their social status has mostly been prescribed by birth. Most closed class systems are found in less industrialized countries.
A social status of a person that is acquired, such as being an Olympic athlete, being a criminal, or being a college professor.
Though the extent to which individuals have social mobility in the United States is debated, new members of the elite are evidence that there is some mobility between classes. President Barack Obama was born to a family without wealth and faced racial discrimination, but achieved the highest office in the country as a result of his personal achievements.
In modern western Europe, status depends on individual educational and professional attainment, meaning that people are ranked based on achieved status.
In medieval Europe, status depended on one's family history, as nobility was inherited rather than attained through occupational success. Thus, people were ranked by ascribed status.
Social stratification describes the socioeconomic levels of a society as "layers," with the wealthiest and most powerful citizens being at the top. Typically, the top layer of society tends to have lots of property, as well as prestige and social influence.
Sociologists who study stratification have identified open class systems and compared them to closed class systems. The difference between these types of class systems are their structural mobility. In a class system that has high structural mobility, it's easy to move around between social classes based on the way the society is structured, regardless of your individual achievements.
In an open class system, the hierarchical social status of a person is achieved through their effort. These types of class systems are achievement-based economic system with social mobility and relations between classes. Status based on family background, ethnicity, gender, and religion, which is also known as "ascribed status," is less important. In an open class system, there is no distinct line between the classes, and there is a wide range of positions within each status level. Core industrial nations seem to have more of an ideal open class system than less industrialized countries, in which there are fewer opportunities for economic advancement.
Compared with industrialized open systems, pre-industrial societies have mostly been found to be closed class systems where there is low social mobility. People in such societies may be confined to their ancestral occupations, and their social status is largely prescribed by status at birth. A society in which traditional or religious caste systems dominate, opportunity for social mobility is unlikely.
Achieved status is a position gained based on merit or achievement (used in an open system). An open system describes a society with mobility between different social classes. Individuals can move up or down in the social rankings; this is unlike closed systems, where individuals are set in one social position for life despite their achievements. Ascribed status is based on who a person is, not what they can do. In closed class systems, people tend to be ranked by ascribed status. When ascribed status is used to determine social position, fixed roles develop, such as those of lord and serf in feudal Europe. Roles are assigned at birth, and there is little change over one's lifetime. Social mobility is much more frequent in countries that use achievement as the basis for status.
