The famous men in black are forcing these governments to enjact unpopular policies to cut spending, which are creating a huge tension in countries like Greece. Take measures to arrange the different countries that have debt problems in order to make them solvent is absolutely necessary to keep Euro safe and to maintain the Eurozone competitive, but not only spending is the point to retail, earnings may also be revised and fiscal policies from countries that are solvent may be applied in failing countries. If a country cannot reach the european competitive standard, rescue and troika policies will be very harmful for the country and the best solution would be to quit the eurozone in order to rearrange the country internally without outside pressure.
We all know that globalization took us to the "crisis", financial speculation in the house market precipitated it and after some years countries realized that the key for going out this trap is being competitive in this globalized world. Debt is not a problem if a country is competitive and grow.
The spanish case special. Some areas of Spain are competitive, but the government doesn't care about developing a social-economic policy in order to boost productivity not only in the competitive areas but also in the rest of the country. The richest and more competitive region of Spain (Catalunya) feels that the rest of the country is just waiting for them to pay the highest taxes of the country so they can receive their money and live over their possibilities. Meanwhile they don't make the necessary investments in the region in order to keep this competitive position in the world. This discrimination is giving wings to the nationalist party which wants the independence and if it occurs, the rest of Spain would face a situation worse than the Greek one.
Conclusion: The way out the crisis is productivity and countries that don't put as a first priority socio-economic necessities and don't solve their intern social tensions will be likely to default and won't have a position in this competitive world.
