Greece achieved a primary government budget surplus in 2013. In April 2014, Greece returned to the global bond market as it successfully sold €3 billion worth of five-year government bonds at a yield of 4.95%. Greece returned to growth after six years of economic decline in the second quarter of 2014, and was the Eurozone's fastest-growing economy in the third quarter.
How can a country be prospering when there is 25% unemployment and whose economy got shrunk by 20%?
Greece is just trying to stay afloat by making promises & deals to borrow more.
