I hadn't seen this so thank you. Bernanke is naturally one of the Central bank experts, so his opinion will carry great weight.
The first time I heard it suggested that Germany should either agree to the eurobond or leave the EU was the Soros speech in Frankfurt. It made complete sense according to my understanding of the way modern monetary policy should be handled in a world of fiat currencies. I have been an advocate of that idea ever since. I hope it comes to pass, and I think it will eventually, as more and more European Heads of State realize how essential it is to their country's economic well-being that a common bond be adopted. Of course this would be somewhat of a mixed bag for Germany, whether they eventually agree to a eurobond and remain in the union, or exit. They will be OK in any case, but with a eurobond in place and a thoroughly integrated monetary system they would no longer be able to borrow at much lower interest rates than their neighbors.
I will agree with you but for a different reason. I think a country with significant fiscal responsibility like Germany should sever it's EU membership on purpose, not be removed. I know you support the policies of spend and print into oblivion, and the EU is welcome to it as far as I'm concerned. But Germany should escape that madness as much as possible.
