After the economic challenges in Greece, Italy, Spain, and more recently Cyprus, it's becoming obvious that the Southern Europe is still vulnerable.

Changes are needed in the banking and financial systems of these countries, but they cannot be done easily. The measures, as necessary as they are on a long term, are highly unpopular at the moment and the rich member countries and the IMF have somehow become the "bad guys" for negotiating the terms of the loans. 

What's your opinion, is there solidarity between the rich North and the poor South?

Are the austerity and financial measures fair? How else could the creditors have the certainty that they will get their money back without imposing these rules?
