Ardun, You also have to see that ones who are employed probebly half of them are on temporary contracts. Little chance that any Bank will lend them money to buy a house, car etc.
The situation has persisted as long I have been involved with Spain. The construction boom was a god send opportunity. Lack of wisdom, foresight on the part of the politicians, business leaders has resulted in the mess.
I even feel in the current situation a serious jolt to the system in bringing changes can deliver long terms benefits whilst the politicians can blame the crises, IMF, EU, Germany etc, etc. basically everybody accept themselves.
