Germany is very export dependent. How are they going to sell their expensive tools, cars to people who can only pay in junk money? Exports will collapse. And then do you think the German consumer will, with Europe collapsing like a pile of salt in the rain, open up their wallets and produce a internal spending boom? I think not.
That’s true. Self-sufficiency requires a country that has diverse enough natural resources, a large and diverse enough manufacturing base, consumerism by citizens who save, and enough cultural morality for exceptional levels of order and peace. We recently had that for a couple of decades.
