Conflict theory looks at society as a competition for limited resources. This perspective is a macro-level approach most identified with the writings of German philosopher and economist Karl Marx, who saw society as being made up of individuals in different social classes who must compete for social, material, and political resources such as food and housing, employment, education, and leisure time. Social institutions like government, education, and religion reflect this competition in their inherent inequalities and help maintain the unequal social structure. Some individuals and organizations are able to obtain and keep more resources than others, and these “winners” use their power and influence to maintain social institutions. The perpetuation of power results in the perpetuation of oppression. Several theorists suggested variations on this basic theme like Polish-Austrian sociologist Ludwig Gumplowicz (1838–1909) who expanded on Marx’s ideas by arguing that war and conquest are the bases of civilizations. He believed that cultural and ethnic conflicts led to states being identified and defined by a dominant group that had power over other groups (Irving, 2007). German sociologist Max Weber (1864–1920) agreed with Marx but also believed that, in addition to economic inequalities, inequalities of political power and social structure cause conflict. Weber noted that different groups were affected differently based on education, race, and gender, and that people’s reactions to inequality were moderated by class differences and rates of social mobility, as well as by perceptions about the legitimacy of those in power. A reader of Marx, Georg Simmel believed that conflict can help integrate and stabilize a society. He said that the intensity of the conflict varies depending on the emotional involvement of the parties, the degree of solidarity within the opposing groups, and the clarity and limited nature of the goals. Simmel also showed that groups work to create internal solidarity, centralize power, and reduce dissent. The stronger the bond, the weaker the discord. Resolving conflicts can reduce tension and hostility and can pave the way for future agreements. In the 1930s and 1940s, German philosophers, known as the Frankfurt School, developed critical theory as an elaboration on Marxist principles. Critical theory is an expansion of conflict theory and is broader than just sociology, incorporating other social sciences and philosophy. A critical theory is a holistic theory and attempts to address structural issues causing inequality. It must explain what’s wrong in current social reality, identify the people who can make changes, and provide practical goals for social transformation (Horkeimer, 1982). More recently, inequality based on gender or race has been explained in a similar manner and has identified institutionalized power structures that help to maintain inequality between groups. Janet Saltzman Chafetz (1941–2006) presented a model of feminist theory that attempts to explain the forces that maintain gender inequality as well as a theory of how such a system can be changed (Turner, 2003). Similarly, critical race theory grew out of a critical analysis of race and racism from a legal point of view. Critical race theory looks at structural inequality based on white privilege and associated wealth, power, and prestige. Sociology in the Real World Farming and Locavores: How Sociological Perspectives Might View Food Consumption The consumption of food is a commonplace, daily occurrence. Yet, it can also be associated with important moments in our lives. Eating can be an individual or a group action, and eating habits and customs are influenced by our cultures. In the context of society, our nation’s food system is at the core of numerous social movements, political issues, and economic debates. Any of these factors might become a topic of sociological study. A structural-functional approach to the topic of food consumption might analyze the role of the agriculture industry within the nation’s economy and how this has changed from the early days of manual-labor farming to modern mechanized production. Another might study the different functions of processes in food production, from farming and harvesting to flashy packaging and mass consumerism. A conflict theorist might be interested in the power differentials present in the regulation of food, by exploring where people’s right to information intersects with corporations’ drive for profit and how the government mediates those interests. Or a conflict theorist might examine the power and powerlessness experienced by local farmers versus large farming conglomerates, such as the documentary Food Inc., which depicts as resulting from Monsanto’s patenting of seed technology. Another topic of study might be how nutrition varies between different social classes. A sociologist viewing food consumption through a symbolic interactionist lens would be more interested in microlevel topics, such as the symbolic use of food in religious rituals, or the role it plays in the social interaction of a family dinner. This perspective might also explore the interactions among group members who identify themselves based on their sharing a particular diet, such as vegetarians (people who don’t eat meat) or locavores (people who strive to eat locally produced food). Criticism Just as structural functionalism was criticized for focusing too much on the stability of societies, conflict theory has been criticized because it tends to focus on conflict to the exclusion of recognizing stability. Many social structures are extremely stable or have gradually progressed over time rather than changing abruptly as conflict theory would suggest.
