I agree, but only so far. There is also the enormous amount of corruption that keeps these political machines opaque and inaccessable to the public, by design.
My point isn't that we are blameless, but that this has been forced upon us in varying degrees. Our options each election year are purposefully limited, and no matter the campaign promise, we get the same results each time--and those are the officials we have a modicum of control over through elections.
We're responsible for fixing it, but distrust in the system is an integral part of fixing it.
