In Greece a third of people under 25 is unemployed

The usual rubbish from ignorant or deliberately mendacious journalists. Greek under-25 Unemployment Rate in 2010, according to Eurostat, was 33%. That means 33% of the labour force ie (those who have a job + those who are officially seeking one). That excludes all under-25s who are inactive, principally due to education.

In Greece 2010, Eurostat reports an activity rate for the under-25s of 30%. That means, applying the unemployment rate to that to which it properly applies, the percentage of Greek under-25s that are seeking employment is 30/33%, or 10%.

That's not to belittle the importance of youth unemployment, just to say that this is false statistics in the service of a narrative.

Fixed.
