The rescue of Ireland inflames the markets and leave Spain and Portugal under the magnifying glass

As expected for weeks, the Irish government gave in to pressure from the euro-zone and finally asked for help to avoid performing an imminent bankruptcy. This aid, which did not exceed 100,000 milions €, will be provided by the EU and the IMF, making Ireland the second country in the accurate euro after Greece.
This announcement caused a great upheaval in the markets, affecting mainly to Spain and Portugal, "powers" that are being watched very closely by the fear of being the next to call for help. The case of Spain particular concern in the international arena, since the adjustment would require greater financial outlay by the assisting state. These fears have risen sharply over the spread of the risk premium on bonds of the Iberian states, thereby increasing the risk of default.
Looking back, I remember a time when these countries, known as PIGS (Portugal, Ireland, Greece and Spain), were the living image of the European miracle, achieving enviable growth rates, how can it be that these rates are now growing so much trouble?
These countries joined the EU in little more than a decade apart, since the entry of Ireland in 1973 to the entry of Spain and Portugal in 1986, passing through Greece in 1981. These four states join the EU with a primarily agrarian economic structure or primary, and suffer a major change in a short time until tercializar its economy without creating an industrial structure stable and strong enough on which to support the economy in a crisis situation tertiary sectors of these.
These seemed to grow as economies driven reactors, it is now clear that this was not a miracle, are, rather, a trick of a conjurer who flattered us. But the reality was that these pigs get fat victims feed calls about low interest rates and credit expansion, inducing slowly insane growth, collapsing the arteries of the financial system with bad investment after a while it caused a failure of that cost recovery.
There is no doubt that each one gathers what he sows and in those countries are paying the consequences of not having the foundation of a healthy and solid growth.
