We have a family friend who moved to rural Greece just before it fell apart with her Welsh husband and little boy. She inherited the family homestead in a breath taking mountain village by the sea and had spent every Summer there as a child. She is native to the area and is a Greek National, and had planned to renovate the villa as a B and B.
Her most recent facebook post was something like "ah, life in a rural village: fridge full of cherries, many jars of apricot jam and several jars of grape, all from the neighbors."
She has been posted updates on the hardships in Athens, but things are not as harsh where she is because people have gardens and small holdings, even if there is little outside work and tourism is down to pretty much zero.
Of course, because she is married to a UK national, if things did get violent or just too harsh to feed themselves; she and her family would be allowed to live in the UK even under the proposed "border controls" if Greece self-destructs the UK is talking about putting in place.
I know there are areas of the country side that are not doing so well, especially urban towns and small ports that relied on tourists that show no sign of coming this year. But the villages, for now, seem the best place to be; at least until the majority of the populations of the cities flees towards them.
This really is starting to resemble the last days of the Roman Empire in a lot of ways (and I don't just mean in Greece).
