the primary purpose of a central bank is supposed to be to prevent inflation. that is a central bank's democratic mandate - it's purpose in a free society. europe had managed to achieve almost zero inflation. this is a great victory, in fact, for the people over the plutocrats. but, as soon as you allow the bank to operate without oversight, they show up at the brookings institute and start making speeches about how they're putting "unconventional" policies in place to increase inflation.
in neo-fascist europe, inflation regulates banks!
