That’s not quite how Martin Feldstein puts it but it is what he means:
The French government just doesn’t seem to understand the real implications of the euro, the single currency that France shares with 16 other European Union countries.
French officials have now reacted to the prospect of a credit rating downgrade by lashing out at Britain. The head of the central bank, Christian Noyer, has argued that the rating agencies should begin by downgrading Britain. The finance minister, Francois Baroin, recently declared that, “You’d rather be French than British in economic terms.” And even the French Prime minister, Francois Fillar, noted that Britain had higher debt and larger deficits than France.
French officials apparently don’t recognize the importance of the fact that Britain is outside the eurozone, and therefore has its own currency, which means that there is no risk that Britain will default on its debt. When interest and principal on British government debt come due, the British government can always create additional pounds to meet those obligations. By contrast, the French government and the French central bank cannot create euros.
Just further proof that there hasn’t been a Frenchman who understands economics since Frederic Bastiat and he died in 1850.
