Have not read it all but OP is spot on in many areas. I left Eire, the Republic, Southern Ireland or simply Ireland in 87 against a backdrop of 25% unemployment.
It is a difficult place to live and you only have to look at my parents generation to see how hard the people could be. My uncle tell a story. He lives in UK and one of his hardier relatives from back home came to do some work with him in the UK. They popped around to a clients hse and rang the door bell. The clients son answered the door with a pet rat on his shoulder. My uncle's relative said nothing just bent over and grabbed the rat and twisted it's neck. All hell broke loose.
My grandfather used to hang stray dogs and leave them hanging for days. Strange man. Funnily enough he though the English women were the best in the world.
My grandmother was a 'matched' marriage to same grandfather who loved English women. He was in his 50's she was in her 30's I think or 20's.
Ireland has had a tough recent history. My mother did not have an indoor bathroom/toilet until I was three in 1971. She already had 4 kids by then. She didn't have electricity until the mid 50's. I am sure this poverty and tough existence has an effect on the people.
The church's hold over people was frightening. Not sure how bad now but when I was a kid it was dreadful.
The education is not great. I am so tired of hearing Irish people banging on about the great system. It's not!!!
The healthcare is not great either. I am speaking about the West here though.
GAA is shite.
Gaelic is shite.
On the plus side I think the women are tougher.
There is more craic.
The scenery is great.
The food is good.
Ireland is a strange, beguiling ,frustrating ,hellish, wonderful place to live. I couldn't go back there.
