I do not see how the European union can survive on its current form. The world needs something to compete with the U.S. Dollar which is a terribly flawed currency. The Euro currency in theory would be good for the world. Unfortunately it was badly executed, a good theory badly executed and now we have many problems.
So, I do not expect the Euro currency to survive and I doubt the European Union will survive as we know it. Because since Brexit occurred it has encouraged many separatists in Europe that want to split up their countries from the EU.
As I expect bad financial times to come, when we have bad financial times, people always look for big change.
