I suppose, if I’m honest, I subconsciously divide people into ‘middle class’ (for want of a better word) and ‘lower class’. But it has nothing to do with money. I know two people who are very rich, live in big detached houses and send their kids to private schools. However, I think of them as ‘lower class’ because they are both vulgar and ignorant. I also know someone who is in debt, rents from the housing association and lives in a sh*t neighbourhood, but I consider her ‘middle class’ because of her beautiful manners and love of reading.
For me, the big dividers are taste, manners, education, reading habits and ability to hold a civilised conversation. You can give a vulgar, ignorant oaf twenty million pounds, but he’ll still be a vulgar, ignorant oaf.
Middle class signifiers: visits art galleries, reads great literature (Nabokov, Virginia Woolf, Jane Austen, Dickens...whatever), loves beautiful things (cathedrals, antiques, the countryside), has refined manners, can hold a civilised conversation (i.e doesn’t boast or show off, listens to what you say, doesn’t talk over you, smiles, maintains eye contact, etc), never thinks about class.
Lower class signifiers: charmless, flashy, vulgar, loud, brash, pushy, pretentious, petty, unrefined, graceless, overbearing, obsessed with celebrity gossip, reads The Sun, watches Love Island, incapable of holding a conversation, never read a serious book, judges everyone by money and status.
