Hopefully some of you who have little or no international experience will understand, after watching that video, what I have been saying about the culture in certain parts of the world. And it's not just Kenya, it is all over the place.
They have no moral or practical problems with cheating--none at all. This is why their cultures don't progress anywhere--because they have no appreciation of the fact that by cheating "others", they are cheating their own societies and, ultimately, themselves. You can't build any kind of meaningful society on such a moral basis, which is why such places in the world are backward--either primitive, or authoritarian/totalitarian.
Things like moral consideration, and sacrificing the immediate personal good for the extended social good by, for example, following the rule of law, are only manifest in evolved societies. People often require a tangible example of the benefits they can expect--i.e. one has to be able to go for a safe walk in a nice park to understand that there are larger benefits that flow from them not mugging somebody else, or not throwing their trash in a ditch.
People in doping places have no such examples, and therefore do not conform their behavior beyond immediate personal gratification--and by personal, I include immediate family and friends, but no further.
So-called "first worlder's" should never project their moral values onto such people. They just do not apply.
Welcome to the globe. If you get a chance, travel and hang around with locals everywhere, and you will begin to understand.
