Can you have local community when you don’t need to have it?

Pseudonymous comment on Carlone Carter’s article on street parties, in the Economist:

‘…when people are poor, vulnerable etc, they need to support each other. When people are rich they don't. Perhaps it is in human nature for people not to care about each other once they are not vulnerable...or perhaps its a negative externality of our neoliberal society. Perhaps you need government intervention..as when my local council sent out SMSs asking us to check on neighbours since apparently people have been dying at home without anybody knowing. Surely what ever the cause, the decline in community is not a thing we should aspire to.’
