Holden, some of us have studied history and political science...and not just the 'publik skool' pablum...since before you were born. For some, the founding of the republic is part of their family history.
The fascist oligarchs who now rule the world do so with the consent of the governed. We no longer have a functional republic because the people are immoral, dumbed down and ignorant. The oligarchs have usurped authority which was never granted, because the generally dumb masses are apathetic, lazy, selfish, irresponsible, parasitic children. The people are deceived and no longer retain any understanding of their own natural rights, responsibilities and authority.
Government granted privileges can be voted away on a mere political whim through the democratic process. The modern jury trial sham is a perfect example. Take two men chosen for jury duty...the democratic man will think "one man, one vote" and will do as instructed by the judge. The republican man will understand...one man has three votes.
Rights are inherent, something possessed by the natural man. They will only be retained if the people are educated and willing to enforce them.
