There are a few different elites here.
It's not as straightforward as aristocrats at the top and proles at the bottom (being flippant here). There are different categories of people, all middle class in my opinion.
For example, a church of Ireland middle class especially if they have the money to send their children to a private school.
Then there is a middle class which is very Established. ie, great grandchildren of Eamon de Valera or some such deeply entrenched entwinement with IRELAND, grandchildren of of other political families. Known by all and sundry for miles around as The ..........Linehans (example) Even people whose grandparents and parents knew how to ''work'' the civil service before about 1985. I don't mean clerical officers.
There is also a more straightforward middle class which is just linked obviously to how well they've done for themselves through their professions or businesses.
There is a catholic middle class that benefits from being RESPECTABLE, white, irish and going back a few generations. Not just the blackrock college / MOUNTanville brigade but also, did your Mother/father go to this normal state catholic school? good, then you're on the A waiting list for a very good state education, unlike the foreigners who haven't a chance. Thank you good bye!
I think the whole gaelgoir thing is a way of claiming a new middle class ground. We are going to send our children to all irish schools so that they get a good leg up and high points and are off to a flying start.
So there's a lot more variance in the middle classes in Ireland.
There are boxes that people can put you in but it's not the only box with the label middle class so people aren't walking around terrified that they said the word mantlepiece in public.
