well, it's an infographic, which usually don't introduce new findings, rather summarizes existing info in an easy to digest way, they provide perspective.

Maybe so, but this didn't come across as an infographic whose purpose was to summarize information. Rather, it seems like a lecture to Americans about certain well-known and thoroughly discussed problems -- a lecture whose points the majority of Americans who read HN undoubtedly already agree with.

While the way to change things as an engineer is often to make something better than the alternative, one way to change things in politics is to keep the issue actively in discussion until public perception reaches a tipping point that something must be done. There are posts on HN about a new version of Rails or an interesting architecture used by a startup not just because it's new but also because it's the state of the industry and we want to dissect it and respond to it. We hear the same arguments about American policy because it remains the state of the country and we want to respond to it.

Good snarking! And on a serious note, I think the main comment here isn't about the actual issues, it's about Americans reaction to them. We appear to be OK with this or at least not willing to do enough about it.
