The class differentials in Turkish society seem to be the real story. The conflict between the material and the spiritual world seems to be a reach that they shoe-horned into the article.
There are some choice examples in this article of the rich religious. My favorite is the sofa that lifts up off of the ground during prayer time.
I wonder how far they had to dig to find people who saw a strong dichotomy between being wealthy and being religious. I think this quote "The businessmen describe themselves as Muslims with a Protestant work ethic, and say hard work deepens faith," is rather telling. How many Turks are thinking of the Protestant work ethic?
