That's an insane idea. Almost none of the important Western thinkers were ever in danger of being peasants. Even at the beginning, when Christianity was still for outsiders, the big thinkers - bishops, monks, scholars, etc. - were almost always children of the handful of rich early converts, rather than peasants. There is absolutely nothing about the history of Christianity to support the idea that its "basic tenets" somehow helped important Western "big thinkers" get where they were by, I dunno, pulling themselves up by their bootstraps? Or something like that?
