If questions about the Slovenian banking sector remain unanswered; if worries about French competitiveness remain unaddressed; if an ageing German society cannot better integrate migrants into the labour market – this has an impact on all countries of the single currency zone. It is therefore right and legitimate, that the euro area countries establish – and accept – much closer oversight of national decisions.
Other countries may see this differently. But the euro area has to move ahead with deeper union. Like it or not, the euro area has become the engine of European integration, for its own sake, and that of the EU as a whole. This process is not a threat to the idea of the European Union.
