Americans: fix your healthcare system.
I vote and I protest, but yet those with money continue to corrupt the system. I feel much more like a victim of the system than a participant. How would you suggest a typical American HN reader go about effecting change?
If you really want change, then you need to somehow climb the ladder of power and enact the changes yourself. Unfortunately, if you take the political or corporate path, you will most likely be so disillusioned by the time you get anywhere that you will join the other side.
You can also become a revolutionary of sorts, by leading others through your charisma or prose.
Of course none of these are anything a "typical" person can do, but in fact, a "typical" person really has no power whatsoever unless someone atypical manages to organize them together.
