What is socialism?

The blog Socialism Or Your Money Back has posted a short Q&A concerning socialism. It's an interesting read - here.

For some reason or another, I'm practically always labeled a socialist on every political quiz I take. In fact, I believe that's been my answer every time. However, the main reason I'm not a socialist is because I'm enough of a realist to know it wouldn't work. Human nature is never going away, and people are greedy. They don't want to share. People want to be the best, they want the nicest things, and they want to be lazy. While socialism could work in communes and very small communities, and certain aspects could be worked successfully into our world (such as workers having a lot of rights), capitalism, at least at the moment, isn't going anywhere.
