Yes, disappointment over perceived unfairness, injustice, promises not kept, tends to go hand in hand with increasing prosperity. Expectations are dashed. What can I say!

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.

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.

Any great organization can go through sectarian phases.

Just in our lifetime our society has become looser and more private, it becomes extremely difficult to hold to any permanent commitment whatever, least of all to organized religion.

It's unlikely that the organized religions will get more sectarian... or is it? I am not at all sure.

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.
