The upper middle class is a sociological concept referring to the social group constituted by higher-status members of the middle class. This is in contrast to the term "lower middle class", which is used for the group at the opposite end of the middle class stratum, and to the broader term "middle class". There is considerable debate as to how the upper middle class might be defined. According to sociologist Max Weber the upper middle class consists of well-educated professionals with graduate degrees and comfortable incomes.

The American upper middle class is defined similarly using income, education and occupation as the predominant indicators. In the United States, the upper middle class is defined as consisting mostly of white collar professionals who not only have above-average personal incomes and advanced educational degrees but also a higher degree of autonomy in their work. The main occupational tasks of upper middle class individuals tend to center on conceptualizing, consulting, and instruction.

The middle class is a class of people in the middle of a societal hierarchy. In Weberian socio-economic terms, the middle class is the broad group of people in contemporary society who fall socio-economically between the working class and upper class. The common measures of what constitutes middle class vary significantly between cultures.

The term "middle class" is first attested in James Bradshaw's 1745 pamphlet Scheme to prevent running Irish Wools to France. The term has had several, sometimes contradictory, meanings. It was once defined by exception as an intermediate social class between the nobility and the peasantry of Europe.^{[by whom?]} While the nobility owned the countryside, and the peasantry worked the countryside, a new bourgeoisie (literally "town-dwellers") arose around mercantile functions in the city. Another definition equated the middle class to the original meaning of capitalist: someone with so much capital that they could rival nobles. By this definition, only millionaires and billionaires are middle class in modern times. In fact, to be a capital-owning millionaire was the essential criterion of the middle class in the industrial revolution. In France, the middle classes helped drive the French Revolution.

Robert Clark "Bob" Seger (born May 6, 1945) is an American rock and roll singer-songwriter, guitarist and pianist.

As a locally successful Detroit-area artist, he performed and recorded as Bob Seger and the Last Heard and Bob Seger System throughout the 1960s. By the early 1970s, he had dropped the "System" from his recordings, and he continued to strive for broader success with other various bands. In 1973, he put together The Silver Bullet Band, an evolving group of Detroit-area musicians, with whom he became most successful. In 1976, he achieved a national breakout with the album Night Moves. On his studio albums, he also worked extensively with the Alabama-based Muscle Shoals Rhythm Section, which appeared on several of Seger's best-selling singles and albums.

A roots rocker with a classic raspy, shouting voice, Seger wrote and recorded songs that dealt with blue-collar themes and was an exemplar of heartland rock. Seger has recorded many hits, including "Night Moves", "Turn the Page", "We've Got Tonight", "Against the Wind", and "Like a Rock", and also co-wrote the Eagles' number-one hit "Heartache Tonight". His iconic recording of "Old Time Rock and Roll" was named one of the Songs of the Century in 2001.
