Quote from Debaser82:
People say it makes no (economic) sense at all for a Greek farmer and a German factory worker to share the same currency.
It's an supposed anomaly that benefits neither the Greek nor the German.
Why does it makes sense for an Alabama farmer and a New York banker to share the same currency?
Only because they both feel 'American'?
This Alabama/New York is a stupid premise. Why just Alabama farmers? What about upstate NY farmers? Or how about Long Island wine growers? After all, it is 2 different economies.
We use the same currency because we all are governed by the same federal system. And the US dollar is the by product of this federal system. Greece and Germany and Ireland are not of the same federal system. They have their own sovereignty and there-in lies the conflict.
