Semantics could help save the euro zone. There is a crying need to distinguish between fiscal austerity and structural reform.  The endless austerity programs adopted by the GIIPS — Greece, Ireland, Italy, Portugal and Spain — threaten to crush their economies so much that they are socially unbearable. By contrast, reforming pensions, labor markets and the like would be good for long-term growth. A policy mix that emphasizes the latter and draws some sort of line under the former is needed to stop the euro crisis spinning out of control.
