Communism is a system that works to everyone's advantage. On paper, it looks like it would be a wonderful economic system to implement. However, it wass never taken off paper and fully implemented in any country; there is always a person or people who stand in the way.

Its a far stretch, but sort of the same principal as karma in the sense that you were talking. Karma is a real thing, and it happens in everyone's life, every day. However, just like Communism, if you wish to suppress people with the principal of Karma, you can. The Roman Catholic Church used a system of monetary pardons only a few hundred years ago. There is obviously something great about Christianity apart from the fact that the Roman Catholic Church abuses it, and there is also something great about the principal of Karma even though there are occurrences in the world like those you mentioned.
