The Kubus scheme was a scheme that originated in South Africa in the 1980s and was subsequently exported to the United States. It involved the cultivation of milk yeast cultures, which was sold to the originator, and the recultivating of the next batch. The producers had to canvass new members to the organisation to ensure sustainability. The whole scheme crashed when the government decided to implement a law in retrospect, thereby declaring the scheme illegal. The originator had to pay back all the money to claimants, likewise all who benefited had to return their earnings.
