Interesting how everyone seems to think about upper classes. I thought about working vs middle-class.
Interesting point. It may be related to a transatlantic cultural glitch.
My first read of the thread title brought to mind an American idiom: If a person is considered to "Have Class" it means that they are tactful, tolerant, stable in demeanor, probably, at least, a bit more sophisticated in arts and sciences than the general hoi poloi.... as I said, above, Style and Grace. "Class" being the difference between MOMA habituees and Walmart shoppers. Even the Wallmart crowd believes that one brilliant scam and a ton of Hard Work can elevate them to Trumphood.
Rereading the thread title through less reflexive knowledge of British culture, derived from extensive studies of Dickens, Kipling, Wodehouse, Python, and Inspector Morse, and the obligatory age-19 "Piss Tour" of the British Isles (1978); I realize that the British notion of class is different, at heart, than the American notion of "Class."
Americans are instilled with the delusion, from a young age, when we study The Constitution, The Declaration of Independence, and the Revolutionary, so called, Founding Fathers in school; that America is a "Classless Society." i.e. that we are not bound to the Caste of our Fathers or inherited Dynastic Titles. Every individual allegedly has the opportunity to better (or worsen) their Lot in Life through Hard Work, (Sloth) or Cleverness; regardless of the position of their father.
Separated by a common language, Selah.
