Fascism and communism are forms of socialism since they operate under the assumption that the Government controls everything. The reason Stalin did not like Hitler was because he thought Hitler's brand of socialism wasn't oppressive enough to the civilians, and, when comparing different socialist governments, the degree of oppression towards its citizens is the real question to ask. Also, just make sure we're on the same page, how does the survey define "quality of life"? As to why the United States is not on the survey, perhaps you should ask the person who made the survey and not me.
But, in any event, I created the meme as a joke for those who have friends and family members that think there has never been an example of a socialist regime that failed in the past. If you are curious about the history and facts of socialism, I can recommend good books for you to read. If you are just looking to pick a fight (which I doubt, but I'm not leaving it out of the possibility since I do not know who you are in real life and vice versa), then perhaps the conversation should end here before it turns ugly.
I'm willing to discuss topics with people, but I'm not interested in participating in another internet chat room quarrel. I sincerely hope you feel the same way.
