Ok, @Mooshamoo, I think your view of class in both Ireland and the UK is very un-nuanced. I’m Irish, born into the bottom of the working-class (dad a bin man, grandads on both sides unskilled labourers, no one went to school past 13 till I did), got out of my immediate circumstances via education, moved to the UK to study at postgrad level and lived and worked there for 25 years before returning to Ireland.
Of course there’s a class system in Ireland, albeit differently stratified to that of the UK as a far less industrialised society till fairly recently. I left Ireland a WC woman, I came back as someone perceived to be MC (multiple postgraduate degrees, educated register, professional career, house in an ‘old money’ part of the city, etc). I’ve been up and down the class system in both countries. I went to an elite UK university and have UC friends, but anyone who asks what part of the city I’m from here will ‘place’ me immediately.
I don’t recognise the Ireland you describe any more than I do a UK full of ‘hard, cold’ people. The reason most people tend to marry within their class is the same here as elsewhere — you mostly socialise in your own class. I married another ‘educated WC’ man who also has multiple degrees and is successful.
But the stuff about needing a wealthy father to be marriageable is nonsense. Poor people and single parents are often looked down on, appallingly, across many countries — it’s not unique to here. And having a degree is pretty normal here — Ireland has something like the fifth most educated workforce in the OECD stats. I don’t have a single friend of my generation (means-assessed grants era) who doesn’t have at least one.
Education is far more socially mixed here. DS goes to a city centre school along with the kids of our cleaner and the kids of our architect.
