One thing that France's Le Pen gets right: The flawed fundamental architecture of European economic policy.
Marine Le Pen and the National Front probably have no chance of winning France's upcoming presidential election. But according to Matthew Yglesias at Vox, they get one thing right: Europe's problems with a single currency.
Beyond this ideological grab-bag is a thoroughgoing and persuasive critique of European monetary arrangements (they also have a persuasive critique of the EU's deeply misguided directive on passenger railroad regulation). They cite Milton Friedman as an authority on the idea that the Eurozone is not an optimal currency area, and this is in fact the professional consensus. They rightly say that the inability of Eurozone member states to conduct independent monetary policy "condemns the people to austerity plans that do nothing but exacerbate the crisis." They say that "France should prepare, with its European partners, a return to national currencies that will permit a return to competitive devaluations" and this would, indeed, be a boon to the French (and Spanish and Italian and Belgian, etc.) economies.
As he adds later, "Le Pen deserves to be confronted where she's making the most sense, not the least."
