Can you provide evidence in support of that claim?
A test for culture/genetics might be found in immigrants. Particularly those that do not immigrate to big expat communities. Even those might be interesting to look at. I think you'll find that people bend quite a distance to what their environment is. I dare say American expats participate in corrupt practices.
My own take on this is that corruption can hit a point where it is the system of government. It's not that dirty cops are cops that started taking bribes & then got used to it. They take the job in the first place in order to accept bribes. If you take away corruption, you take away the police.

Same goes for many other elements.
