In the late 19th Century George Cadbury anguished over slavery in the cocoa plantations. A hundred years later they were threatening those trying to expose it — including sovereign governments. They denied it existed and even now keep saying they are going to investigate it. Back then, the humanitarian concern was such that Britain boycotted cocoa beans from Portuguese San Tome and Principe. Today, the prospect of a boycott results in lectures about the need for the free market and how it will harm families that rely on cocoa farming to provide them a subsistence living.
