Don't be ridiculous. The north has always been richer and more industrialized than the south. The current GDP disparity is purely due to European Union monetary influence in recent years, and joining the single currency... and you know it (I hope).
In fact. the Republic of Ireland was very close to bankruptcy only a few years ago.. until they were bailed out by the European Union (and, in effect, also by tax money from Northern Ireland residents...).
