In the Atlantic, Hanna Rosin asks the musical question, Did Christianity Cause the Crash?.

Rosin goes to nondenominational “megachurches” that preach the “prosperity gospel,” often to minority and immigrant churchgoers. Her implied allegation: These churches’ leaders were in cahoots with the big-yet-shady bankers and lenders, delivering the naive faithful into often disastrous mortgages and investment schemes.

To this I’d say yeah, maybe; but a lot of other influences were at play too.
