Obviously there is snobbery and class division in Ireland, but you would never ever see class discussed so openly on an Irish forum.
It's a bit taboo to discuss it in Ireland outside your own rank :-p.
Also, in the UK some very ordinary people pretend to be a cut above buttermilk. If it was obvious even to a foreigner that they were a bit fake I dread to think how obvious it was to the Brits!
Meanwhile in Ireland, I think posh people play it down a bit, or at least, have a chameleon-like ability to assimilate. Look at Richard Boyd-Barrett. I admire him and his background is privileged and educated but his accent changes with the wind.
Also, another difference between the classes in Ireland and Britain that mobility is allowed. At the top of the food chain, newcomers are allowed so long as they play by the rules.
The Middletons would be admired in Ireland. They came from humble origins and worked hard at their own business and spent their own money on their children's education, a nice house, a good life.. That would be more admired in Ireland I think.
In Ireland there are a whole load of different clues! I spot if people say cupboard or press!
