Ken Rogoff, is one of the great economic minds out there and his book, “This Time is Different “, is probably the best read of the 2008 crisis and the structural issues surrounding. 
At the core Rogoff says, with no growth how to you solve debt problems. No magic formula or Keynesian stimulus will work. Says to do what U.S. also needs to be.
Need for infrastructure investment, Rogoff cites the Boston big dig, $20 billion after estimated at $2 billion, but says unions made it a mess. Is it really attempting to do something or just a transfer of wealth and programs for refurbishing schools.
Europe needs a central government and there is no way 17 different voices will solve problems and find solutions. Euro will not hold up with same existing “orbit” of players. European Central Bank has played things well but only bought time.
No fundamental problems have been solved.
