It's true that in the West "we have chosen to replace God with the self". But of course that is only the ego self. According to Jung, however, there is a deeper self which turns out to be the God image in a human. I think it was Jung, but if not him then someone else, who said that "the self is naturally religious". That is the reason that modern society, not just Capitalism but the whole of the 'Enlightenment' mentality, is so dangerous for humanity; it is trying to persuade us to deny our human nature.
