I'm just pointing out that there is at least one candidate who want to change things. Rather than complain that things will never change, one could go to work supporting and promoting politicians who would fix things. An example is http://www.revolutionpac.com/ which is basically a bunch of regular folks, political outsiders, getting together to produce and air commercials for Ron Paul. It's never been so easy to organize and communicate. Declaring that "there's nothing we can do" has never been more false.
Personally, I support Ron Paul. While I don't agree with all of his policies, he seems like the sanest guy up there. Still, HN is for discussion of tech, start ups, and cool new things in our world; not politics. Any political discussion will quickly devolve into ad hominem attacks, and provide no interesting commentary. If you want to discuss politics, head over to one of the many forums, subreddits or discussion boards about politics, but this is not the place.
