Christianity. Say what you want about Christianity itself — I'm not arguing for or against it — but I believe that it's because those are the societies in which a Christian morality was prevalent. A key aspect of Christian morality is fairness: do unto others..., pay people what you owe them, don't accept (or give) bribes. Corruption opposes those values and can't thrive in a society that embraces them. If those values don't exist then corruption has a chance.
