No system of government will suffice, for we were never intended to be governed.
We seem to forget that we were tribal grazers and hunters for millions of years from the time we abandoned the arboreal lifestyle; operating in small, tight knit groups that solved their problems from within the group, not without. In the blink of an eye, geologically speaking, we have hoisted an incredibly violent, complex, and demanding world onto our minds. It's no wonder there is so much war, inequality, and insanity in today's world. We stand blinded by our technological achievments to the reality that our minds and bodies did not evolve in the present age, nor did they evolve for it. Once we planted that first row of wheat we set down a path that, 16,000 years later, finds man consuming the entire world. One can only guess how long we have artificially been raising the carrying capacity of the Earth, and how long we can sustain it.
