Peter Schiff gives a great talk which covers quite a lot of ground. What is money? How did the world leave the gold standard? What are the consequences? Is capitalism or the free market to blame?
This talk was apparently given as a part of a bigger event with other speakers, including Ron Paul.
Got this video from Håkan Kindström Arnoldson, it does a great job of providing a somewhat oversimplified argument for the gold standard, but nevertheless the overall outcome is really good :)
