Having just posted on communism killing more than 100 million people, a friend alerted me to something I should listen to. It was a post on Karl Marx.
I won't reinvent the wheel on this one. Visit Captain Capitalism's post and if you enjoy podcasts, take the time to listen to the one linked. I did, and it made me understand how the theories behind communism arose from Karl Marx. The short version is that he was a sick and twisted man who expected others to support him because he believed he was too important to work. Communism now makes sense, doesn't it? Now go read the post and listen to the podcast.
