Spanish work ethics may not be blamed for the current crises. The issue is much bigger & it has to do with the mentality & their thinking.
It should not have taken them long to realise that no sector of any economy can go on forever. Spaniards should have known this and planned ahead, living for the day, work shy, try & get away with as little work as possible, lack of care & pride in the work produced, desire to improve & educate oneself, time keeping, taking responsibilty.
If I am a multi national and I have an option to invest in Poland or Spain. I will not be investing in Spain for reasons stated above. (not to mention labour laws, unions. This of course has nothing to do with the employees )
