Anyway, back to the point. Spain, Italy have a lot of fine craftsmen - remember Zara, Ferrari and Lamborghini! But the Northerners are pretty professional at their work - BMW, Volvo, Nokia! It will take long for the mindset in the southern states to change from casual to the one of performance.
As the pressure mounts, a lot of young people will start to gravitate towards greener pastures in other countries - it's easy for people from member states to move to a new country, thus depriving these countries of young workers. It'll turn out to be a pretty painful situation them, a brain/workforce drain, which is the last thing they want right now.
The EU and Euro currency brings both good and bad. The good that I see is the easy exchange of money, travel and work options. The bad is that European people aren't a single stock, they don't like to be compared to each other, or to be put on similar benchmarks. It was smart move by Switzerland and UK to stay out of the Euro currency. The common currency puts a pressure on everyone to be equal. And that, is not going to happen. This will be a challenge EU will face for a very long time to come, and maybe there's no good answer.
