This brings to mind Jean-Baptiste Queru's (Yes, that JBQ, the head of AOSP) 2015 post regarding the structural problems inherent in the EU's fiscal policy. Read it: whether you agree with his analysis or not, it will make you stop and think.
He's advocating for fiscal union, but in paractice this requires a "United States of Europe". The proud nations of Europe don't appear to be ready for this level of union yet.
It's an open question whether the current crisis is a long term step away, or will lead to the relatively radical reformation required to achieve closer union.
What's really the point of us stopping and thinking about it.
I'd like to see Larry Page, Jack Dorsey and Mark Zuckerberg think about it. Cause its the same story with the Billions they have accumulated. Unsustainable.
