There was no such support when the monetary union was created and little has changed since. In the midst of the crisis, I do not see sufficient willingness on the part of EU governments or citizens – neither in Germany nor elsewhere – to actually transfer sovereign rights on budget issues to the European level.
Merely increasing mutual liability – by introducing eurobonds, for example – without establishing greater mutual control in return, would only provide additional incentive to incur debt. After all, you wouldn’t entrust your credit card to someone if you weren’t able to control their spending. For the time being, therefore, the only answer to the crisis is to strengthen the Maastricht framework.
