Earlier quoted context omitted.
Are you suggesting that all the people in countries like Cambodia are "corrupt"?
I am suggesting that it's more than the elites, then you'd have to take into account the people who would act in a corrupt way if presented with the opportunity. As someone who has tried and failed to sell software into Cambodia I know from experience that the corruption there is very thorough and continues well on down to the lower strata of society.
Trying to sell software into Cambodia puts you squarely in a procurement situation where you're going to encounter the patronage networks that are responsible for the corruption.
So since you seem to be suggesting the Cambodians have a disposition towards "act[ing] in a corrupt way if presented with the opportunity" (versus, say, Americans who you seem to think just elect corrupt politicians but have no disposition towards corruption themselves), why don't you share your experiences with the "lower strata" of Cambodian society as a software salesman?
