One of the primary reasons for that change stems from diminished participation in church service.
Maybe so, but when my age was in single-digits, my mother made me go to Sunday School (until I figured out she just wanted a quiet day and me being far away worked just as well). It didn't take me long to figure out their hypocrisy. The minister's son was the most obsequious little shit I have ever met.
Fun fact: I came first in the 'bible studies' test despite completing it in 25% of the allocated time and treating it as fairy stories. These were not the brightest. Yes, I'm bragging :-)
So - I rather resent the idea that church makes good people. Dostoevsky observed that "without god, everything is permitted". Quite. So it's down to us to be good because it's right, not because we'll burn in hell if we don't.
As far as business is concerned - I worked for DEC for many years. The founder, Ken Olsen was a decent man (a devout christian, too) who, I think, tried to do the best for his employees. Maybe it was easier in the boom years. Eventually he was ousted by the board, and a cut-throat CEO was installed, who oversaw the dismantling of the enterprise. I think he made out ok though.
