Hmm, I don't like Capitalism, I think it leads to terrible things and I also dont think that it works. It is good in exploiting people and the environment in order to produce goods cheaply, but very bad in fulfilling human needs. Just look at how much more productive whe have become (by exploiting workers at home and abroad and destroying our planet) , still, there are people without homes (even in the west) and we still have to work 40+ hours a week. Also, I dont think this is the right way to discuss this (I mean over a message board). In response to your original point:
- just because people do not believe in capitalism does not mean they believe in the government
- the question of human nature is a hen and egg thing - you might argue that greed is what drives people, I'd say greed is one of our attributes, but capitalism really plays to it. There are other societies that are not based on greed and they have been much better of (a good read in this respect is "ancient futures").
Still, good to see that people talk about these things.
