Sometimes a country becomes so overridden by debt that it actually
makes sense for it to default, abandon its currency and start over.
Greece is not one of those countries.That hasn't stopped a number of economists from arguing otherwise, however, and Prime Minister Alexis Tsipras's statement that he may call a referendum on any deal with creditors suggests Greeks might soon be asked to make a choice. If they are, they should trust their instincts (insofar as they can be measured by opinion polls) and stick with the euro.
