It is funny. Many years ago we were not allowed to carry or read any books written by Marx, Engels, Lenin, Stalin, Trotsky, or Mao,( We had to carry them inside of a Playboy magazine ) and several peoples were killed, taken to jail and tortured because of that, and now a group of commercial publishers are claiming private ownership over the works of Marx and Engels.It was a capital sin to read, or to talk about Marx and Engels.We were allowed to read the mental poison published by the Catholic church, and American ambassadors, the police, the military and the priests had never read anything about them, and they were against them, or were anti-communists, for most of those policemen Marx and Engels were just a couples of baseball playersSeveral government in Latin America under the strict order the US government they had to place a rubber stamp on the passport of every citizen which used to say: You are not allowed to travel to Russia or any of its satellite including China, Eastern Europe, North Korea and Cuba, and several friends of mine who studied at the University of Patrice Lumumba were taken to jail when they returned after they became medical doctors or engineersMany years ago Progress Publishers, Albanian Publishing House, and China International Publishing House were giving for free the works of Marx and Engels. I had a complete closet full of books ( from the bottom to the top ) that I had to give away to members of different organizations given to me for free by China Books and Periodicals.I am glad that I purchased, read and collected all those books when I was very young because the prices are going up and many peoples are not going to read them
