There is a soviet joke. Two workers in France discuss, one really wants to move to the soviet union, the paradise for workers, the land of plenty. The other is more hesitant, he also heard stories of famine and repression. All capitalist propaganda, says the first one, and I made up my mind, I am going. Well, says the other one, I might join you, but first you go, and you tell me how it is, and if it is what you say it is, I go too. But if it is what those capitalists say it is, you might not be free to write your mind so let's devise a code: if you can write freely, write in black ink, if you are coerced, use red ink, and I will know I shouldn't come. A month later, he receives a letter, in black ink, saying "the soviet union is fantastic, workers are really cared for here, we have freedom, food, prosperity, everyone is happy. The only inconvenience is that I really cannot find any red ink anywhere".
