"Let each give according to his abilities and receive according to his needs" is not that far from Christian doctrine?
Yes, it is a Christian way but, of course, not the principle belief that Jesus is the Saviour. I was going to say that, while it is a Christian way, Christians do not exhibit the same corrupting influence as is seen in communist regimes. But my current study of the history of Christianity shows man's inbuilt selfishness and love of power/money has always created problems - that's why the selflessness of the first, Apostle-taught churches was so exeptional.
Maybe there is a big diffeence between Comunism and communialism? The genorosity of Greek people, particularly those in villages, is an exampe of the latter term and so too is the barter system with foodstuff.
The cheerfulness of the Greeks I meet everyday is astounding and gives me great hope for the Nation's future.
