Summary: some guy made a speech in 1984 that aims to convince you that the United States, err, ancient Rome, screwed up by going off the gold/silver standard. (Note that it's from mises.org)
Well, by not just coming off the standard but by constantly debasing their currency, constantly increasing taxes, not preventing counterfitting, and putting the state into the hands of the military.
Ignore this idiot. His summary is wrong, In his haste to make a snarky comment he missed the entire point of the transcript.
