The 19 Member States of the Eurozone cover some 4,422,773 km² of territory, much of that is densely populated. The geographic area of Australia covers 7,682,300 km² and is mostly sparsely populated. The reason density matters is because it impacts on the resources that need to be expended to provide infrastructure across the geographic space. In the past month, the French people have elected a new President and a dramatically different National Assembly. In his election campaign, Emmanuel Macron spoke of being part of a major reform process for the dysfunctional Eurozone. To create some federal fiscal capacity including the idea of debt-mutualisation (issuing Euro-level debt) to match spending on public infrastructure etc, which could help to revitalise the stagnation that besets many regions across the currency union. In 2012, François Hollande was also elected on a reform ticket. The same day he was elected he visited Angela Merkel in Germany. The reform process ended before it started. He went away with no uncertainty about what the Germans would tolerate as masters of the union. Well within a short-time of being elected, Emmanuel Macron has also received his instructions from the Germans, this time in the guise of remarks made by Bundesbank boss Jens Weidmann. The orders are clear. Germany will never tolerate the creation of anything like a functioning federal fiscal capacity. End of story. Macron now knows the limits of his volition. What are the limits of being confined to a straitjacket?
