Some parts of Europe was a economic disaster a long time ago and still are. Most of Europe is doing very well just as US.
Well if you can say that somebody is doing well while their debt is constantly going up than OK. Also after the 2008 crisis that was just poorly fixed and hiden!
Personally I don't think anything is going fine and very soon a new, big boom is imminent. Hope I am wrong but it doesn't feel that way.
The economic crisis hit US first later Europe. US is now fully recovering and Europe will follow. The main problem now is the fall in Gold and oil prices that will continue for a long time. Land with a real export of good will do good.
I think Greece will need some help if you want full recovery. I don't see them being saved unless some of the eurozone do a bailout.
I could be wrong on it though. I don't see the other countries letting Greece fail though.
