The only way for Greece to rebuild it’s economy is to leave the EU. They are going through horrible times right now, but if they face their problems now, they will have a better chance of coming out the other side stronger than they have been for a long time.
When I was younger I struggled financially. When I looked at it honestly, a lot of it was my fault. Believe me, that was not a pleasant conversation to have with the wife. It took a lot of struggle, but we came through it stronger than ever, not only in our finances, but also our relationship. But honestly looking at the situation gave us the path to getting out of debt. Greece needs to do the same thing. You can also throw in Italy, Spain, and Portugal to the mix.
