As I implied earlier, my view is that the German establishment and the 'Brussels dictatorship' refer to the AfD as "far right", useing it as a term of abuse, preferring to accentuate it's (sensible) policies about immigration, but it's other political concern and policy - and how it came into being - is if anything rather "left", and scares them more, which is a call for the abolition of the rigid eurozone which has created such suffering to the poorer members.
The economist, Martin Wolf has said, "The euro has been a disaster, no other word will do". He points out that The United States had a strong political union and national banking system before it created a currency union. Europe went at the project from the other direction. Nations within the euro cannot conduct their own monetary policy, if they need to increase exports they can only increase productivity via higher unemployment and lower wages.
As Wolf says The Shifts and Shocks "The mechanism of the Eurozone adjustment is simply that of the old gold standard, and forces misery on nations in the name of preserving a stable exchange rate".
How much longer the eurozone (and the EU itself) can continue in its present form is open to debate.
