"Communism doesn't work, because people like to own stuff."
1) People do like to own things, and have power. Communism doesn't work. Some people tend to want what other people have, and that alone causes problems. With communism, people will try to tell on others to get more 'stuff'.

2) Currently I am reading a book called "Breaking Stalin's nose", and it's about communism. A little boy wants to be a pioneer, and he thinks that communism is great. In the book, the boy (Sasha) claims that he wouldn't be surprised if someone in a capitalist country has never tried a carrot before, since he never visited a capitalist country before. Sasha thinks Stalin is great, and so does everyone else. In reality, Stalin wasn't a good person. In the story, Sasha is starting to learn that communism also isn't so great, because Sasha starts out as a model student, but after he accidentally knocks off Stalin's nose (from a statue), someone tells on him, and Sasha is getting punished as if he meant to do it.
 
3) I think this picture goes with the quote, because 2 people are fighting over something, and in communism they take all private property away, but people want stuff. Communism doesn't work out that often, as I said before, people tend to get jealous and want things other people have and that leads to constant fighting.
