"But I do think you might have noticed something about the price of food, gasoline, and so on"

As for profits: take tourism. Salaries in tourism (not uncompetitive vis a vis the real competitors to begin with) have plummeted while the "opening" of professions has reduced what was once jobs you could make a living off to hobbies... At the same time the large units that work with foreign tourism, are not seeing any decrease in revenues (internal tourism is a different issue, it has been wiped out). So the big hotel owners are making money at the expense of their workers...

Frankly, Greece and especially Athens could stand a revamp on that score since there are far too many cars on the road.

But food?

Greece went from 20% imports to 80% in a decade. Greece is the largest importer of French beef, and 15 years ago, Greeks were not beef eaters at all (relatively). In other words, the dynamic has very quickly changed Greek eating habits as well as Greek agriculture. Greece would revert in any devaluation.

Oil is a big concern, of course.
