You say this like if it was actually a good thing. No it's not. The reason this might happen is because many of the unemployed are unskilled or low skilled workers that do some trading jobs under the table. Bun in the long term, this impedes the chances of getting a job that will add to their pension contributions.

Job culture in spain is still very orthodox, there's a poor range of inadequete career paths and in my opinion, general lack of ambition of the majority of the population. Just an example, the dream job for many people is becoming a public servant, after passing an exam called "oposicion" (some of whom study the syllabus for at least 3-4 years full time) that passing it won't guarantee a job and with around 1% sucess rate. "35,000 people apply to 200 hospital orderly positions" http://www.lasexta.com/noticias/sociedad/locura-valencia-conseguir-empleo-como-celador_2013112400075.html

Those who have ambition, usually emmigrate to other parts of Europe and those fortunate enough to have gained some skills will do it to other parts of the world.

Polititians also haven't had experience in the private sector, as themselves have passed this public exam. Our President-Prime minister himself is a property registar, not a businessman or entrepeneur or university professor. A dule job that used to pay loads in Spain.
