This is a no brainer. The falling tax revenues in Greece are going to have a severe impact on it's socialized economy because employment depends on government spending. When the former Soviet Union collapsed, unemployment soared.
Eventually, if the private sector is allowed to come into the economy, the economy will greatly improve and become much more dynamic. But here is the rub: going through the mess can be a bitch. Social unrest? Likely. Violence? Great possibility. It's unfortunate, but when an economy implodes because of government meddling, the consequence looks like Greece.
Think that this can't happen here? You might want to think again.
