Personally, I've come to realize that capitalism, communism, socialism are simply semantic pits that don't really mean anything. If you say these words to people they have wildly different interpretations of their definitions and the arguments that arise from this discord are usually both heated and pointless.

Words are meant to communicate things, if they aren't communicating your intent then why even bother using them? While they still have some vague relevance from a historical perspective, like when discussing the cold war, I think any contemporary discussion where one feels the use of these words might be necessary would be better off just listing their ideals directly instead of falling into this semantic trap.
