I'll be very brief.
The whole European Union is in collapse!
If the exit of Greece from the Euro Zone is required, this will be the beginning of the end.
After Greece, will be Portugal, Ireland, Italy, Spain....
In my opinion, there are only two solutions:
1 - On one hand, start to produce a greater amount of money. And, consequently, increase the amount of aid;
2 - On the other hand, excuse the countries of the existing debts and start again from zero.
