I think you're wrong, there. I remember the last time that, "History is irrelevant! We'll make our own decisions!" was the cry. I can remember that many, if not most, were the same mistakes that had already been tried before.
* Most of the Founders of the United States of America were well grounded in history, and what had been tried and failed, or tried and succeeded. They created our Constitution to avoid the pitfalls they saw in history, and set up a land where the people could be free, and in charge. It wasn't perfect, but it worked pretty well for over a century.
* They, and many others warned repeatedly that to retain our Constitutional government and nation required constant vigilance, for the wealthy, the banks, the magnates would always be looking for ways to subvert or overthrow and control it.
* When the idea of history became what was had for breakfast yesterday, we seem to have lost our caution, our need to reaffirm our Constitution and Bill of Rights for our own protection.
* Sure enough, the banksters and other criminals quietly came in and bought the government for their own use.
* Thomas Jefferson wrote, “The two enemies of the people are criminals and government, so let us tie the second down with the chains of the Constitution so the second will not become the legalized version of the first." We allowed those chains to rust and lose their strength and now the shattered links lie forgotten, just as most now have forgotten our Constitution and Bill of Rights.
* He also wrote, “The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants. It is its natural manure.”
* That old tree is looking pretty droopy. Perhaps it needs a good manuring.
