Every year the progress of advanced capitalist society makes our population consist of more and more isolates. This is because of the infrastructure of the economy, especially electronic communications.
I am sure it must be true that people opt out of the mainstream society because they feel that there are going to be no rewards for them, if they stay.
Our technological infrastructure alienates us from each other. No need to form a workplace community, everybody there will be out in a year or two, and so will you, looking for a better place.
Mormons... are so strong, they can handle wealth, they are confident. I think it is because they are not bogged down by rules for equality, but have a firmly defined system of relative status and responsible command.
Inside a religious body you get sects and hierarchies, inside an information network you get bazaars and cathedrals, it is the same, call them what you like. They survive by pointing the finger of blame at each other.
It is only partly true that religion does more harm than good in society. The community makes God into the image it wants, vengeful, or milky sweet, or scrupulously just, and so on.
