In agrarian sociology, landlords are defined as individuals who hold legal title to land but rely on tenants or laborers to perform the actual farming. This distinction is central to understanding class structures in rural societies, where ownership is separated from the physical labor of production.

The reputational method relies on community members ranking the social standing of others based on their perceived prestige. This method is highly effective in small, stable communities where residents know each other well. It becomes impractical in large, transient, or densely populated urban areas where individuals lack the intimate knowledge required to accurately assess the social status of their neighbors.

In sociological terms, 'new money' refers to wealth that has been acquired by an individual during their own lifetime, often through entrepreneurship or professional success, as opposed to 'old money,' which is inherited wealth passed down through generations. This distinction is often used to analyze class status and social mobility.

Karl Marx argued that the fundamental division in capitalist society is between the bourgeoisie, who own the means of production (property, factories, land), and the proletariat, who must sell their labor power to survive. Therefore, the ownership of property is the defining factor that creates the class structure and the resulting social inequality in a capitalist system.

Social class is a multidimensional construct in sociology. It is not defined by a single variable but by a combination of socioeconomic indicators including wealth (assets), income (earnings), and education (human capital). These factors collectively determine an individual's or group's position within the social hierarchy and their access to life chances and societal resources.

Social class acts as a primary determinant of social relations because it dictates the resources, environment, and social circles available to an individual. People within the same social class often share similar life experiences, values, and opportunities, which facilitates stronger social bonds and interactions within that specific stratum.

The American Dream is a national ethos suggesting that through hard work, courage, and determination, any individual can achieve prosperity and success. It is fundamentally built on the belief in equal opportunity for all citizens regardless of their social background.

The term 'working class' is frequently used in sociological literature to denote the lower socioeconomic stratum of society. This group typically consists of individuals who perform manual labor or service-sector jobs, often characterized by lower levels of income, education, and social prestige compared to the middle and upper classes.

Standard of living is a multifaceted concept that measures the level of wealth, comfort, material goods, and necessities available to a certain socioeconomic class or geographic area. It is determined by various indicators, including employment rates, access to property, and disposable income, which collectively reflect the economic well-being and quality of life of a population.

Erik Olin Wright's theory of contradictory class locations posits that some positions in the capitalist structure, such as managers or supervisors, occupy a space between the bourgeoisie and the proletariat. They possess some control over the means of production while also being subject to the authority of owners. The provided answer key suggests they are impossible to measure, though Wright actually developed a complex framework to classify them.
