In any transition period there is a clash of realities. In the 1930s people considered the eventual solutions, at first, to be unrealistic. It's the same this time round. At first, in the euro crisis there was to be no bailout. Then no buying of government debt. Then no QE. Each of these things have happened. Some things which are now seen as unrealistic will change with the political balance of forces.
