Other EU countries have taken on huge debts to support Greece only to be berated by Syriza; Spain for example has given Greece 27 billion euro (equal to an entire year of government social spending) while Spain itself suffers 25% unemployment and a collapsed economy. Syriza has/is rolling back many reforms (like paying civil servants 13 months pay every year) while other EU country are continuing to cut back (e.g. on retirement ages). Many EU countries (e.g. the Baltic states) have lower average salaries and work longer before retiring than the Greeks and yet have paid into the rescue fund for Greece. After all this Syriza still blames the EU for their troubles? Or threatens to unleash Jihadists on Berlin?
The trouble with Greece is that the government hasn't balanced its books in 35 years and the economy produces little of value (olive growing and cheap tourist sector jobs) while expecting to live a live-style like the average German, British or even French or Italian who produce high value-add goods which are exported to the world. They continue to demand that the government spend more while avoiding taxes.
Syriza feeds this national self-pity by looking for outsiders (particularly the Germans) to blame for this. At some stage reality has to be faced.
