There is class in Ireland too, RipRC but it is more subtle than in the UK and people don't openly refer to it. Some of it is reverse snobbery too - a posh accent could actually hinder your career in Ireland, for example. Class / money awareness is there, though, if you meet certain people.
Where I grew up in the West of Ireland, we all just mucked in together whatever your parents did for a living and I had almost no class consciousness at all. When I went to university in Dublin, however, I met quite a few class conscious types there (D4 brigade
) but just thought they were deluded eejits mostly. There were also British people studying at my university who had a whole structure in their heads about public/private school, areas they lived etc that was relevant to them that meant nothing to me.
It did sometimes annoy me in the UK, when I lived there, how much people made assumptions about my 'class' based on their own cultural preconceptions, assuming I was from a privileged background. Northern English people seemed especially obsessed with telling me they had grown up in a council house or were working class, even if they had a PhD and/or a lot of money. They seemed embarrassed or preoccupied about class in some way. At the other end of the scale you had the fawning over the aristocracy/upper class which I found puzzling in this day and age (and I'm sure a lot of sane British people would agree with me there).
I was raised to view aristocrats as pathetic exploitative parasites, irrelevant to any developed culture. When I lived in the UK and heard people refer to 'Sir' this or 'the Honorable' that in some admiring way, I really had to bite my tongue so I didn't offend anyone and fulfill the stereotype of the chippy Irish trouble-maker.
Every country has different socio-economic classes but in the UK people refer more openly to it and talk pointedly about it in terms of working/middle/upper class maybe.
