The EU has some dark times ahead, mind you its in its infancy but even factoring in growing pains as a new system/currency; its not a pretty beginning.
The obvious problem is when you join all these different countries together its difficult to rule them properly as an economic system.
However I see dark days ahead for all the world, we'll need a revolution of sorts in how we do business in the future and I think we'll see some of that coming up in the next 50 yrs as the US debt reaches crisis levels and the EU and Asia go through some serious crisis.
I'm in the camp of capitalism sucks but its the best system we have.
