Вам мало СА? Нужны еще примеры? Бритнаской империи пришлось очень долго бодаться со среднем классом Трансвааля и Оранжевой, а средний класс Бостона и прочих американских колоний бритнаскую корону таки забодал.
Понятно. Вы явно считаете средним классом людей с достатком. Хм, ну-ну.
тогда для начала сюда.
The American middle class is an ambiguously defined social class in the United States.[1][2] While the concept remains largely ambiguous in popular opinion and common language use,[3][4] contemporary sociologists have put forward several, more or less congruent, theories on the American middle class. Depending on class model used, the middle class may constitute anywhere from 25% to 66% of households. One of first major studies of White Collar: The American Middle Classes, was made by sociologist C. Wright Mills in 1951. Later sociologists such as Dennis Gilbert of Hamilton College commonly divide the middle class into two sub-groups. Constituting roughly 15% to 20% of households is the upper or professional middle class consisting of highly educated, salaried professionals and managers. Constituting roughly one third of households is the lower middle class consisting mostly of semi-professionals, skilled craftsmen and lower level management.[2][5] Middle class persons commonly have a comfortable standard of living, significant economic security,
considerable work autonomy and
rely on their expertise to sustain themselves.[6]
Everyone wants to believe they are middle class...But this eagerness...has led the definition to be stretched like a bungee cord — used to defend/attack/describe everything...The Drum Major Institute...places the range for middle class at individuals making between $25,000 and $100,000 a year. Ah yes, there's a group of people bound to run into each other while house-hunting.

There is considerable diversity among members of the middle class, who tend to overlap with each other. Overall, middle class persons, especially upper middle class individuals, are characterized by conceptualizing, creating and consulting. Thus, college education is one of the main indicators of middle class status. Largely attributed to the nature of middle class occupations, middle class values tend to emphasize independence, adherence to intrinsic standards, valuing innovation and respecting non-conformity.[6][2]
Politically more active than other demographics, college educated middle class professionals are split.[7] Income varies considerably from near the national median to well in excess of $100,000.[5][2] Household income figures, however, do not always reflect class status and standard of living, as they are largely influenced by the number of income earners and fail to recognize household size. It is therefore possible for a large, dual-earner, lower middle class household to out-earn a small, one-earner, upper middle class household.[6] The middle classes are very influential, as they encompass the majority of voters, writers, teachers, journalists, and editors. Most societal trends in the US originate within the middle classes.[8]
