I may be confused, but doesn't the European Central Bank have a zero percent interest rate set at the moment?
Isn't that a Keynesian stimulus?
Europe let the crises drag on for years, with questions about whether Greece, Portgual and Ireland would even stay in the euro. 0% now is much too little, far too late.
