I don't know any Greeks who are not supplementing their incomes, directly or indirectly with a number of extras like olive oil production, eggs, beans, shops, restaurants and crops galore. Even an Athenian consultant surgeon acquaintance of mine has his parents producing all his food needs on the home farm he will eventually inherit and retire to in order to produce essentials for his 4 kids which all go to private schools and are heading for high-flying university studies and posts.
All other countries would have crumbled by now given the same mess Greece has been dealt. Greece is the vanguard of strength, resilience and the continued civilised world order.
Greece is a strange mix of the intellectual and the peasant (Cyprus mirrors this). And I LOVE it so!
