Ask HN: How to repair a country?

I come from a country that is not only financially unstable, but the corruption is very high. That country is Greece.

Here is a pastebin from a longer description if you don't mind reading: https://www.pastiebin.com/59f2f738cf269

Atm Greece is definitely not on the right path. Its heading towards the wrong direction. Not only financially, the people themselves have accepted that after 10 years of struggles its only gonna become worse and stay like that. The government is so corrupted but noone is going to jail, the Europeans are turning the backs to the problem as long as the Greek Government runs errands for them. I was hoping that being part of Europe meant that they'd help out on situations like that e.g Corrupt Government that needs proper jailtime. Financially nothing is getting better, the debt is only growing longer and longer.

How do you repair Greece? How do you change the mentality, the Government and how do you put Greece back on the right track for financial growth?
