I was talking to an Afrikaans guy whom I know well and trust. He made an interesting remark. He explained to me that a long time ago he was involved in a project where someone wanted to start a private Blood Bank. He told me that during this exercise, he discovered that the one and only Blood Service that we have in South Africa, is actually owned by Jews!
If you donate blood in South Africa, they don’t pay you. But this same blood is later used, then you pay an arm and a leg for it. So they basically get "Free Blood" from donors which they then sell at a great price when it is used for a blood transfusion for example.
