5. Greece
A recent addition to the list of countries facing a brain drain problem, Greece has always had its share of people leaving to work abroad. Ever since the debt crisis exploded in 2008, the situation has become alarming. Some 350,000 people have left Greece between 2010 and 2013. That’s 3% of the entire population gone abroad in just 3 years. 35,000 Greek doctors are working Germany alone. Considering that university education is free in Greece, it seems that at least some of the aid money Germany provided in debt relief has been paid off.
