> That economist explained how the EUR would lead to "too many secondary houses in Spain" and "too many public servants in France".

The part relating to France is the usual small-state BS that has thoroughly corrupted modern "economics". France's problem more is its power generation, they rely on nuclear power, a lot of their fleet is noticeably aged and desperately needs replacement, but such replacement is incredibly expensive. On top of that, French military expenditure is ridiculous, they still dream of being an empire, maintain nuclear weapons and aircraft carriers, that make sharing vessels or aircraft with other European countries a pain - as evidenced by FCAS collapsing, the French wanted to use us Germans as paypigs for their pet project suited to carrier deployments.
