Found this 2014 salary survey of how much professionals earn in regions of Ireland. I had no idea there was such a thing in Ireland! Anyway now I can tell you that a C++ developer in Ireland earns a 10k bump in minimum salary over other developers, but earns just a few thousand more on average. I can also tell you that one only earns an extra 5k for working in Dublin, which surely isn't worth the extra cost of living! Very interesting!
