Despite Ireland having a stunning growth of 5 percent in 2014 and nearly double that in 2015, the country is not isolated from typical growth problems: A burdened transportation infrastructure, a fast growing population that is spending far less on infrastructure growth capital projects, a struggling socialized health system and mortgage issues. The real challenge is how the government will keep up with the demands of the demographics and not choke its ever-narrowing capacity.
The Irish have the lack of fortune to be buddy-buddy with the United Kingdom, and therefore Europe, when things are going good, yet they're tossed to the curb in terms of aid when things are going bad. If there's another recession looming, I'd expect Ireland to be hit hard by it. Not potato famine levels, but certainly more than Great Britain.
Ireland had a period of economic growth before 2007-2008 global financial crisis (it was even called the "Celtic Tiger"), but then their economy suffered like the rest of the EU or even more so. And although Ireland's economy is going strong at the moment, there are no guaranties that they will be able to avoid next big crisis should it hit whole EU.
Since the beginning, Ireland has always been integrated into Europe. Ireland's economic growth is directly tied to the EU. I think that Ireland is a growing country, but it is not ioslated from Europe. During the Eurozone crisis and sovereign debt bailout, Ireland was one of the least isolated countries. Nothing has changed.
