Evidence all all around you. But lets first define what corruption mean… Corruption is the abuse of bestowed power or position to acquired a personal benefit. Now, I will state that greed is one of human nature. All of the countries that are communist have a very strong power structure with a small group of people having all the power. So, it would be obvious that those people who are in power would want to abuse their power to acquire personal benefit. In a democratic system, when the person or group of people are corrupted and the people know about it, they will be voted out of power. In countries like China, Vietnam, Laos, etc., if the people speak up about such corruption, they will disappear. The people are aware of the corruption but they don’t want to say anything, because they rather live. This is why I said communism tend to breed corruption and allow it to be rampant. Plain simple fact is, greed is part of human nature. Communism is great in theory, but I believe communism doesn’t take into consideration that greed is part of human nature and when you allow a small group of people to be in charge and no way for the people to kick them out, you will have corruption.
Keep in mind that I did not say only communist country have corruption. Since greed is part of human nature, I believe corruption will exist everywhere that there are a small group of people with all the power. As I stated, there’s no pure communist country. So, when I say communism, I mean the countries that call themselves communist, not the actual communism theory.
BTW, you’re the one who ask me where I got my information and whether it’s from western media. I told you one of the source where I got my information from, and now you’re saying it doesn’t cut it. So tell me, where do you get your information from? Chinese/Vietnamese/etc media?
