If debt default occurs and spendthrifts like Greece leave the EU, they will have their own currencies – and they will let them depreciate against the euro to boost exports to the EU

Exactly what is Greece going to be exporting in such huge quantities to Germany if their currency falls then?

I really can't think of anything that Greece exports that the world needs. Their biggest industry to my mind are shipping and tourism. One is transporting things from one place to the other ( a valuable service I admit ), the other is living on the glories of the past.
