The Union should be based on the princip that a package of compulsory rules for all members apply only to areas were this is clearly necessary. An example would be that voting power in EU institutions requires that democratic principles and freedom of the press is respected in each memberstate. However, this does not apply to the case of a singel currency. Forcing convergence in this way onto members that do not want it is going to make the union dangerously unstable.

The consequences of low real wage growth depends on the particular situation of the country. In some crisis countries within the eurozone, unit labor costs had become unsustainably high. A real devaluation had to be undertaken and in absence of the possibility to devalue the currency low wage growth is a painful necessity. In other countries, its more the wage profile that has been the problem. Low wage growth for categories of workers who have difficulty finding jobs has been good, for example in Germany. However, higher aggregate wage growth would possibly have been good for Germany and certainly good for weaker countries in the union. Currently, in Sweden, low negotiated wage increases make it difficult for the central bank to receive its inflation target.
