Is a shame the problem of unemployment in Spain, and I'm always wondering how it is possible that there is not a "revolution" with these soaring unemployment rates, close to 30% and higher in some areas. Well, I do not understand it. Economists say it is because of two reasons, first in Spain the family networks are very helpful to each other, in many cases the pensions of parents help the children spendings, etc.. Another reason is the underground economy, which some economists estimated at 20% of GDP, but in some sectors of the economy is probably more than 50%
