-a politically neutral central bank is impossible by definition
-to give credit to anyone who asks had been pretty much the goal of CEB since its creation (wich explains in part the euro crisis)

So protesters are right to protest, but what they revendicate has ever happened, and it's the cause of the Euro crisis. Of course, we should'nt put the same currency for countries of unequal wealth. That each country return to golden standard and their original national currency is probably the best thing, i think.
What I say here can applies to the fed too by the way.
