Should I worry going to Ireland as a Pole?

While speaking about Ireland.... this showed up on my youtube feed and it's interesting, suggesting that economic figures regarding the Irish economy have little to do with reality (Leprechaun economics) and that the country is generally not so well run in that it is bad at things like building infrastructure, managing healthcare and the housing market which is a giant, overpriced mess

Comments (mostly from people in or from or who have lived in Ireland) say it's pretty accurate.

The Irish are the happiest nation in Europe. Poles, despite constant complaining, are also high in the list. So, these two should develop good relations.
