Which type of social mobility describes a change in occupation within the same social class?

Does a person’s appearance indicate class? Can you tell a man’s education level based on his clothing? Do you know a woman’s income by the car she drives?

For sociologists, categorizing class is a fluid science. Sociologists generally identify three levels of class in the United States: upper, middle, and lower class. Within each class, there are many subcategories. Wealth is the most significant way of distinguishing classes, because wealth can be transferred to one’s children and perpetuate the class structure. One economist, J.D. Foster, defines the 20 percent of U.S. citizens’ highest earners as “upper income,” and the lower 20 percent as “lower income.” The remaining 60 percent of the population make up the middle class. But by that distinction, annual household incomes for the middle class range between $25,000 and $100,000 (Mason and Sullivan 2010).

One sociological perspective distinguishes the classes, in part, according to their relative power and control over their lives. The upper class not only have power and control over their own lives but also their social status gives them power and control over others’ lives. The middle class doesn’t generally control other strata of society, but its members do exert control over their own lives. In contrast, the lower class has little control over their work or lives. Below, we will explore the major divisions of U.S. social class and their key subcategories.

Upper Class

The upper class is considered the top, and only the powerful elite get to see the view from there. In the United States, people with extreme wealth make up 1 percent of the population, and they own one-third of the country’s wealth (Beeghley 2008).

Money provides not just access to material goods, but also access to a lot of power. As corporate leaders, members of the upper class make decisions that affect the job status of millions of people. As media owners, they influence the collective identity of the nation. They run the major network television stations, radio broadcasts, newspapers, magazines, publishing houses, and sports franchises. As board members of the most influential colleges and universities, they influence cultural attitudes and values. As philanthropists, they establish foundations to support social causes they believe in. As campaign contributors, they sway politicians and fund campaigns, sometimes to protect their own economic interests.

U.S. society has historically distinguished between “old money” (inherited wealth passed from one generation to the next) and “new money” (wealth you have earned and built yourself). While both types may have equal net worth, they have traditionally held different social standings. People of old money, firmly situated in the upper class for generations, have held high prestige. Their families have socialized them to know the customs, norms, and expectations that come with wealth. Often, the very wealthy don’t work for wages. Some study business or become lawyers in order to manage the family fortune. Others, such as Paris Hilton and Kim Kardashian, capitalize on being a rich socialite and transform that into celebrity status, flaunting a wealthy lifestyle.

However, new-money members of the upper class are not oriented to the customs and mores of the elite. They haven’t gone to the most exclusive schools. They have not established old-money social ties. People with new money might flaunt their wealth, buying sports cars and mansions, but they might still exhibit behaviors attributed to the middle and lower classes.

The Middle Class

Many people consider themselves middle class, but there are differing ideas about what that means. People with annual incomes of $150,000 call themselves middle class, as do people who annually earn $30,000. That helps explain why, in the United States, the middle class is broken into upper and lower subcategories.

Upper-middle-class people tend to hold bachelor’s and postgraduate degrees. They’ve studied subjects such as business, management, law, or medicine. Lower-middle-class members hold bachelor’s degrees from four-year colleges or associate’s degrees from two-year community or technical colleges.

Comfort is a key concept to the middle class. Middle-class people work hard and live fairly comfortable lives. Upper-middle-class people tend to pursue careers that earn comfortable incomes. They provide their families with large homes and nice cars. They may go skiing or boating on vacation. Their children receive high-quality education and healthcare (Gilbert 2010).

In the lower middle class, people hold jobs supervised by members of the upper middle class. They fill technical, lower-level management or administrative support positions. Compared to lower-class work, lower-middle-class jobs carry more prestige and come with slightly higher paychecks. With these incomes, people can afford a decent, mainstream lifestyle, but they struggle to maintain it. They generally don’t have enough income to build significant savings. In addition, their grip on class status is more precarious than in the upper tiers of the class system. When budgets are tight, lower-middle-class people are often the ones to lose their jobs.

The Lower Class

The lower class is also referred to as the working class. Just like the middle and upper classes, the lower class can be divided into subsets: the working class, the working poor, and the underclass. Compared to the lower middle class, lower-class people have less of an educational background and earn smaller incomes. They work jobs that require little prior skill or experience and often do routine tasks under close supervision.

Working-class people, the highest subcategory of the lower class, often land decent jobs in fields like custodial or food service. The work is hands-on and often physically demanding, such as landscaping, cooking, cleaning, or building.

Beneath the working class is the working poor. Like the working class, they have unskilled, low-paying employment. However, their jobs rarely offer benefits such as healthcare or retirement planning, and their positions are often seasonal or temporary. They work as sharecroppers, migrant farm workers, housecleaners, and day laborers. Some are high school dropouts. Some are illiterate, unable to read job ads.

How can people work full-time and still be poor? Even working full-time, millions of the working poor earn incomes too meager to support a family. Minimum wage varies from state to state, but in many states it is approaching $8.00 per hour (Department of Labor 2014). At that rate, working 40 hours a week earns $320. That comes to $16,640 a year, before tax and deductions. Even for a single person, the pay is low. A married couple with children will have a hard time covering expenses.

The underclass is the United States’ lowest tier. Members of the underclass live mainly in inner cities. Many are unemployed or underemployed. Those who do hold jobs typically perform menial tasks for little pay. Some of the underclass are homeless. For many, welfare systems provide a much-needed support through food assistance, medical care, housing, and the like.
