Exchange rates mean nothing. They mean something only to speculators. GBPUSD was at 30 or even higher at some point in time. UK still exists, although not an empire. EU will still exist after EURUSD goes to 0.5 but it will not have hopes for a high place in reserves of central banks. They should have known this when they admitted 17 more poor nations in EU. It is now a long shot. They need to print money, print and print again, or revert to local currencies. This is the story in a few lines. Accept inflation and EUR devaluation, or revert to local currencies.
