The way I see it, at least in France, it's not really a question of religion. "The rich" are thought to have acquired their wealth doing dubious things, mostly by "exploiting the poor".

There's also a very strongly egalitarian way of thinking, as in pretty much everybody is interchangeable. So, if someone does better than somebody else, it's likely because of something "unfair" (or luck) and not thanks to being more competent.
