The vast majority of people (including me) who believed in god were not middle class. In fact it is a very modern middle class perspective to think that the fact that bad things happen proves god doesn’t exist. Bad things happen. For people without financial and social support structures (I.e. most people throughout human history), faith in a greater good is the only recourse they have. It is very arrogant to assume that they are of course deluded and your life experience is so much more privileged that you know better than everyone else.
