Needing to be more neighbourly

Much has been said about the many people who, when all this started offered to be a voluntary carer in some way. But why? If we all cared in the first place then there should be little extra to do except organise. There are some great examples of communities setting up care cover for their various neighbours. Fantastic. But again, why were we not at that level of caring in the first place ? How come so many folk living in hamlet, villages and towns feel so isolated and lonely. Even when they have people living next door to them.? Canna get my head around just when this society of ours started to not care so much? With a few exceptions.
