If you've got young kids or plan to have them and want to give your kids the best possible opportunity in life, you probably ought to be considering moving to Ireland (or even somewhere else in the EU if you can get a visa) so that your kids can get a European Union nationality. Then they won't have to post on a thread like this in the future.
There doesn't seem to be much migration between northern and southern Europe though. Probably because most EU countries have prosperous areas within them even if they are poorer on average. For example, people from the poor areas of southern Italy can migrate to the wealthy region around Milan. Same is now becoming true for the former Communist countries. Polish people are now flocking from the countryside to the major Polish cities where good jobs are now available, so there is less of a desire to go abroad. Maybe not paying as much as in Germany or the UK but because of the lower cost of living they can now enjoy an almost western European standard of living without needing to travel far away from friends and family.
I’m not sure how much convergence there has been in the existing EU nations. There’s a noticeable gap in GDP per capita between the Northern countries such as Germany or the Scandinavians, and the Southern ones like Spain and Greece. Especially with the Eurozone there’s a definite tension between the different economies that no longer have the release of currency fluctuations.
