Greek civil servants are 3.3% of the population, less than that of Germany. What about the rest of 96.7% of population who are getting crushed. How does punishing the 96.7% fix the problem of crony corruption.
The share of public worker sector workers out of overall employment was 29% in Greece vs 19% in Germany and they earned 49% more per hour than private sector employees (in Germany the difference was 19%). Source: http://www.ecb.europa.eu/pub/pdf/scpwps/ecbwp1406.pdf
This is not a problem of "crony corruption". It's the same problem you see in Central and South America - voters who think they're entitled to Northern European levels of services without having a Northern European economy.
